EBB Weapon Redesign
Summary
Removed all flute weapon code, fixed several gameplay initialization issues, then shifted to a deep weapon design exploration — building a systematic vocabulary of attack shapes, behaviors, triggers, and scaling patterns, and using it to generate 22 new emoji-matched weapon concepts.
Flute Code Removal:
- User was unsatisfied with the flute weapon from the previous session and wanted all code removed
- Identified and removed flute-related code from 19 locations across
main.yue: image declarations (flute,musical_note), physics tags (note_projectile), note-wall collision handler, flute scaling on hit,'f'key debug binding, flute weapon config block in ball class (lines 1340-1358), commented-out flute AI firing code, flute weapon drawing, three flute methods (flute_is_aligned,flute_snap_angle,flute_fire), ball_board weapon image chain and trail rate stats display, note/note_trail projectile setup, sensor shape branch, trail timer, trail spawning, note drawing, note/note_trail wall hit handling, and'flute'from headless_weapons list - Changed default headless player weapon from
'flute'to'sword'
Ball Spawn Position Fix:
- Enemy ball was spawning at
@w*0.9, @h*0.1(far right, near top) — asymmetric from player - Changed to
@w*0.75, @h/2to properly mirror player position (@w*0.25, @h/2)
Game Auto-Start Fix (Balls Not Moving):
- The
start_movingmethod had been modified for debugging during flute work: gravity set to 0, angle forced to 45°, angular velocity set to 0, and actual movement code commented out - Only the player ball called
start_moving!; the enemy ball just hadset_gravity_scale 0 - Restored original
start_moving: gravity=1, random impulse (an.random\sign!*an.random\float(5, 10)horizontal,an.random\float(-10, 10)vertical),base_angular_velocity - Restored
@enemy_ball\start_moving!call in arena constructor (line 455) - Referenced pre-flute commit
bd43f6dto verify the original behavior
Cooldown Bar Initial Display Fix:
- Weapon auto-attack setup (lines 1390-1401) started each weapon with
_ready = falseand atimer\afterfor the cooldown duration, but never called@cooldown_bar\activatewith the initial cooldown - The cooldown bar started with
@progress = 1and@active = false— invisible during the initial wait - Added
@cooldown_bar\activatecalls with matching cooldown durations (gun:@base_cooldown, sword:@thrust_cooldown, bow:@bow_cooldown) after each weapon'stimer\after
Weapon Design Philosophy — Key Insight:
- Battles are intentionally long (items will speed them up later), so permanent numerical scaling (+damage per hit, orbiting entities) is way too OP
- The existing working weapons (dagger, gun, bow, sword) scale visually — more projectiles, faster rotation, bigger thrusts — creating exciting chaos without breaking balance
- "The visual chaos IS the scaling, not raw damage numbers"
- User wanted to systematically explore the design space rather than invent weapons ad-hoc
Design Space Exploration (created reference/attack-design-space.md):
- Part 1 — Shape Vocabulary: 19 shapes including point, forward line, cone, arc/sweep, full circle, expanding ring, cross burst, orbital, and various projectile paths (straight, bouncing, gravity-arc, returning, spiral, zigzag, homing), plus placed effects (zone, trail, wall effect, trap)
- Part 2 — Behavior Vocabulary: 9 behaviors (continuous, triggered-single, triggered-burst, triggered-volley, channeled, charge-and-release, reactive, periodic/timer, conditional/positional)
- Part 3 — Trigger Vocabulary: 8 triggers (raycast alignment, rotation completion, timer, proximity, wall contact, speed/velocity, accumulation, on-hit)
- Part 4 — Scaling Vocabulary: what's visually good vs numerically dangerous; sweet spot is scaling that is both visible AND naturally bounded
- Part 5 — ~20 interesting shape×behavior×trigger intersections worth considering
- Part 6 — Reassessment of existing todo weapons against the framework
- User specified arena-grounded designs (not abstract PoE shapes), exploration of trigger alternatives beyond raycast, vocabulary-first approach
Emoji-Matched Weapon Concepts (Part 7, 22 weapons):
- New weapons not in original todo: 🧯 Fire Extinguisher (cone spray), 🎣 Fishing Rod (long-range hook), 🪘 Drum (expanding ring shockwaves), 🪩 Disco Ball (star pattern projectiles on rotation), 💣 Bomb (fuse charge → projectile nova), 🔮 Crystal Ball (temporary orbiting shards), 🏓 Ping Pong (long-lived bouncing projectiles), 🍭 Lollipop (spiraling projectiles), 🖌️ Paintbrush (wall-impact damage zones), 🪤 Mouse Trap (periodic minefield), ⛏️ Pickaxe (wall surge shockwave), 🪅 Piñata (spin + periodic candy burst), 🎆 Fireworks (arcing rockets → persistent burst zones), 🪀 Yo-Yo (throw-orbit-catch cycle), ✂️ Scissors (proximity mode switch), 🪁 Kite (speed-triggered bursts), 🎈 Balloon (wall-bounce inflation → nova pop)
- Existing todo weapons reshaped: 🔦 🪃 🪨 💿 🥄 ✏️ ⛓️ 🔔, plus 🔨 reimagined as slam instead of pure rotation
Todo Cleanup:
- Moved all weapon designs (Blocks 1-13 plus status effect system) from
todo.mdto design file under "Appendix: Original Weapon Designs (Pre-Redesign)" with note that they predate the visual scaling framework - Todo now has a pointer to the design file plus remaining non-weapon sections (Other Systems, Classes, Ideas)
Attack Reference Matrix (created docs/ATTACK_REFERENCE.md):
- 4 building block tables with ID codes: Shapes (19), Behaviors (9), Triggers (8), Scaling (8)
- Implemented weapons table mapping dagger/gun/sword/bow to the framework
- New weapon concepts table mapping all 26 weapons to Shape/Behavior/Trigger/Scaling columns
- Design checklist: 6 questions to verify when creating new weapons
- Initially placed next to
main.yue, moved todocs/folder per user request
Hello, Claude. Let's continue work on Emoji Ball Battles, however, we need to back off from implementing weapons for a while and do some redesigns. Last session we implemented part of the flute and I didn't really like it. I tried to make some changes myself but nothing came together quite well. So for now, let's just remove all code related to the flute from the codebase.
Let me start by reading the relevant files to understand the current state of the codebase.

Good, I now have a complete picture of all the flute-related code. Here's what I'll remove:
- Line 87-88:

note_projectilephysics tag and collision - Line 343: Default weapon changed from
'flute'to something else (e.g.'sword') - Lines 527-528:
'f'key flute_fire debug binding - Lines 811-827: Note-wall collision handler

Let me verify there are no remaining flute/note references.
Grep (flute|musical_note|note_projectile|note_trail|'note')
No matches found
Clean. All flute-related code has been removed from main.yue. Here's a summary of what was removed:
- Image declarations:
fluteandmusical_noteasset loading - Physics:
note_projectiletag and its wall collision - Arena: Note-wall collision handler, flute scaling on hit,
'f'key debug binding - Ball class: Flute weapon config block, commented-out AI firing code, flute weapon drawing,
flute_is_aligned,flute_snap_angle, andflute_firemethods - Ball board UI: Flute weapon image mapping and trail rate stats display
- Projectile class:
note/note_trailsetup, sensor branch, trail timer, trail spawning, drawing, and wall hit handling - Headless: Removed
'flute'from weapon list, changed default player weapon to'sword'
OK, now let's fix the spawn positions for the enemy ball, and have the game automatically start as it did before.
Let me read the relevant sections to understand the current spawn positions and game start flow.

The seen_space is unrelated (it's text rendering). The game already has @paused = false so it starts unpaused. Let me check whether there was some kind of initial pause or countdown mechanism that might have been changed recently.

I see two issues you mentioned:
Enemy spawn position: Player is at
@x + @w*0.25, @y + @h/2(left side, vertically centered). Enemy is at@x + @w*0.9, @y + @h*0.1(far right, near the top) — asymmetric. Should be mirrored to@x + @w*0.75, @y + @h/2.Auto-start: You mentioned the game should "automatically start as it did before." The game currently has
@paused = falseand notime_scale = 0on init, so it does start immediately.
Could you clarify what "automatically start as it did before" means? Is there something specific that's not happening — like the AI weapons not firing, or something else? Or was there previously a different initialization that got broken?

User has answered your questions: "What does 'automatically start as it did before' mean? The game currently starts unpaused. Is something specific not working — e.g. AI not firing, balls not moving, a missing countdown, or something else?"="Balls not moving". You can now continue with the user's answers in mind.
Got it — the balls need an initial impulse. Let me check how that used to work.

Now I can see the full picture. The start_moving method has been modified for debugging — gravity is set to 0, angle forced to 45°, angular velocity to 0, and the actual movement code (gravity=1, impulse, angular velocity) is commented out. And only the player ball calls start_moving!, while the enemy ball just gets set_gravity_scale 0.

There was some code added to make sure the weapons start charging their cooldown instead of already ready to fire, but this isn't showing up in the cooldown UI bar.

I see the issue. The weapon auto-attack setup (lines 1390-1401) starts each weapon with _ready = false and a timer\after for the cooldown duration, but it never calls @cooldown_bar\activate with the initial cooldown. So the cooldown bar starts with @progress = 1 and @active = false — it just sits invisible while the actual cooldown timer ticks.
The fix is to add @cooldown_bar\activate calls right after each timer\after in the weapon setup. Let me check what duration each weapon uses.
- Gun:
@base_cooldown - Sword:
@thrust_cooldown - Bow:
@bow_cooldown
Edit (E:\a327ex\emoji-ball-battles\main.yue)
The file E:\a327ex\emoji-ball-battles\main.yue has been updated successfully.
Added @cooldown_bar\activate with the matching cooldown duration to each weapon's auto-attack setup. Now the UI bar will show the initial cooldown filling up instead of being invisible.
OK, now let's do design work. @emoji-ball-battles\todo.md has the current design for weapons we were going to add next. I believe quite a few of them will be added as they are, but there are likely many that will not make it. This is because now that I've thought about the game more I realize that there are certain variables that we weren't taking into account before. For instance, battles take quite a long time, and this is because later we'll want to add items to the game, so it'll be a lot faster, but this means we have to be careful about how things scale. +1 damage per hit is terrible scaling because it's way too OP and makes the battle one-sided immediately. Same for the initial flute design of having notes orbitting around it. Given that battles last long, any permanent effects that add damage are way too strong. Essentially, many of the designs are likely busted on this front.
However, there's another front I ignored which is the "play variety" angle. Consider the existing weapons. Gun, bow and sword all use the raycast to trigger their effects. Dagger is the only one that uses rotation only. Gun and bow are projectiles, and both have special effects that increase the number of projectiles (via attack speed/burst or +arrow count). Sword is fully melee but also uses the raycast. What all these have in common is that as the battle progresses, it gets more chaotic, either with increased projectile count, increased thrust damage, or increased rotation speed. But all these are primarily VISUAL effects. They scale in a nice way against each other and none is too OP, but they also scale in a way that makes the game feel compelling to watch. All weapons should be like this.
There's another componet to it which is the type of attack the weapon has. Dagger is rotation, so it's like a small area around it. Sword is thrust, so it's a line in front of it. Gun fires 1 or 3 shots that bounce many times, so it's kind of a random projectile path/area coverage via lots of projectiles. Bow is the same but it's arrows that don't bounce. We want to explore all possibilities for attacks. So lines to the sides/behind, areas in front, behind, projectile paths that have different behaviors (i.e. boomerang is a good example of this), and then all the ones involving stacked effects which are already in the document. But we want to kind of exhaustively go through these combinations, among with other combinations of shapes + effects, and see what we can come up with. I believe Path of Exile is a really good place to look at for this general theory of attack/spell shapes. There's lines, cones, areas, delayed areas, rings, etc. We should have similar behaviors in our weapons.
What I want you to do is explore this design space. You don't have to tie any of it to specific emojis yet, although it may help. Just the shapes of all attacks (line, cone, area type 1-2-3, etc), against the type of attack (projectile, melee, swing, etc) and see what comes out the other end. I recommend using Path of Exile as a loose reference along these lines. Before you start, I'd like you to tell me if you understand me and if you have any questions.
I understand the core insight well. Let me restate it to make sure:
The scaling problem: Battles are long, so any permanent numerical scaling (damage, orbiting entities, etc.) becomes dominant. The existing weapons that work well scale visually — more projectiles, faster rotation, bigger thrusts — which makes the game more exciting to watch without breaking balance. The visual chaos IS the scaling, not raw damage numbers.
The design space problem: You want to systematically map out attack shapes (line, cone, area, ring, etc.) crossed with attack types/behaviors (rotation, projectile, thrust, beam, etc.) to find the full set of interesting weapon designs, rather than inventing weapons ad-hoc and hoping they're distinct.
Before I start exploring, a few questions:
AskUserQuestion
User has answered your questions: "The arena is a 200x200 box with gravity and bouncy walls. Some PoE shapes (ground-targeted circles, long-range beams, etc.) don't map directly. Should I think about shapes strictly in terms of what's physically meaningful in this arena, or explore more abstractly and we'll figure out the mapping later?"="Arena-grounded", "Currently dagger uses pure rotation, while gun/bow/sword all use the raycast-alignment mechanic (fire when pointing at enemy). Should I treat alignment as a universal mechanic most weapons use, or should some weapons deliberately break from it (e.g. fire in all directions, fire on a timer regardless of aim, fire based on position rather than angle)?"="Explore alternatives", "What format would be most useful for the exploration? A systematic matrix (shape × type grid), a narrative exploration that builds up the vocabulary then combines, or something else?"="Build vocabulary first". You can now continue with the user's answers in mind.
Good, those answers sharpen the scope nicely. Let me think through this carefully and write it up.

Opened the doc in NeoVim. Here's the structure of the exploration:
Part 1 — Shape Vocabulary (19 shapes): Point, Forward Line, Cone, Arc/Sweep, Full Circle, Expanding Ring, Cross Burst, Orbital, then projectile variants (straight, bouncing, gravity-arc, returning, spiral, zigzag, homing), then placed effects (zone, trail, wall effect, trap).
Part 2 — Behavior Vocabulary (9 behaviors): Continuous, Triggered-Single, Triggered-Burst, Triggered-Volley, Channeled, Charge-and-Release, Reactive, Periodic/Timer, Conditional/Positional.
Part 3 — Trigger Vocabulary (8 triggers): Raycast alignment, rotation completion, timer, proximity, wall contact, speed/velocity, accumulation, on-hit.
Part 4 — Scaling Vocabulary: What's visually good vs numerically dangerous. The sweet spot is scaling that is both visible AND naturally bounded (like +arrows, where marginal value decreases).
Part 5 — Interesting Intersections: ~20 specific combinations worth considering, organized by category (forward-directed, radial, projectile variants, placed effects, hybrids, trigger-interesting).
Part 6 — Existing todo reassessment: Which designs survive, which need scaling rework, which shapes from the analysis are completely missing from the current todo.
The most important finding is probably the unexplored shapes — expanding ring/shockwave, cross burst, spiral projectile, wall surge, rotation-triggered nova, impact zones, speed-triggered burst, and movement trail. None of these appear in the current weapon list.
Aboslutely stellar analysis. Now, regardless of the emojis that are already designed, try to match an emoji to each of the combinations in part 5. If you can't find an emoji that fits, you may change the combination itself. Favor the emoji making sense over getting the exact combinations as they were listed there. Add these ideas to the end of the document you just created.
Let me re-read the end of the document so I know where to append.

240→
241→### E. Hybrid / Unusual Combinations
242→
243→**Rotation + Periodic Burst + Rotation-Completion = Spin-and-Fling**
244→Weapon rotates continuously like dagger (contact damage), but every N rotations it RELEASES projectiles tangentially. Like a sprinkler that flings droplets as it spins. Scaling: more projectiles per fling, or more frequent flings. Combines melee presence with projectile escalation. Visually: a spinning weapon periodically scattering projectiles outward.
245→
246→**Charge + Ring + Accumulation = Pulse Bomb**
247→Each HIT on the enemy builds a visible charge. At threshold, releases an expanding damage ring. Scaling: lower threshold (more frequent pulses) or bigger rings. Creates a "building toward something" tension, then a dramatic release. The ring is a distinctive visual punctuation mark.
248→
249→**Tether + Triggered + Alignment = Chain Weapon**
250→Fire a projectile that attaches to the enemy via a chain/rope. While tethered, the chain itself deals damage — anything crossing the line between the two balls takes damage. Scaling: more simultaneous tethers (multiple chains criss-crossing the arena). Visually: lines connecting the balls that other projectiles/effects interact with.
251→
252→**Projectile + Zone-on-Impact + Gravity-Arc = Carpet Bomber**
253→Fire arc projectiles that create small damage zones where they land. Scaling: more projectiles per volley, zones last longer. The arena floor gradually gets covered in overlapping impact zones. Combines the visual of arcing trajectories (air) with persistent zones (ground).
254→
255→**Line + Reactive + On-Wall = Wall Beam**
256→When the ball is touching or near a wall, fire a beam along the wall surface (horizontal or vertical line hugging the wall). Since balls frequently hit walls, this fires often. Scaling: beam gets longer or wider. Creates lines of damage along arena edges — a very different visual from center-of-arena attacks.
257→
258→**Returning + Orbital + Triggered = Yo-Yo**
259→Projectile goes out, then instead of returning directly, orbits the ball once or twice before being "caught" and becoming ready to throw again. Creates a rhythm: throw → orbit → catch → throw. Scaling: more simultaneous yo-yos, or more orbits before catch. The orbiting phase provides melee-like area denial while the throw provides ranged reach.
260→
261→### F. Trigger-Interesting Designs
262→
263→**Proximity-Triggered Mode Switch**
264→Weapon behaves differently based on distance to enemy. Close: continuous rotation damage (dagger-like). Far: fires projectiles (gun-like). Scaling: both modes get more intense. Creates a weapon with two visual identities depending on the state of the fight.
265→
266→**Speed-Triggered Burst**
267→When ball exceeds a speed threshold (from a hard bounce), fires a burst of projectiles in the movement direction. Faster ball = more projectiles in the burst. The weapon converts kinetic energy into attacks. Scaling: lower speed threshold (fires more often) or more projectiles per burst. Ties weapon activity directly to the kinetic energy of the fight.
268→
269→**Wall-Impact Counter**

Now let me think through the emoji matches carefully and append them.

Done. Part 7 has 22 emoji-matched weapon concepts. Here's the quick summary:
New weapons (not in todo):
- 🧯 Fire Extinguisher — continuous short-range cone spray, sweeps with rotation
- 🎣 Fishing Rod — long-range forward line/hook with tug
- 🪘 Drum — periodic expanding ring shockwaves, rotation-independent
- 🪩 Disco Ball — fires projectiles in star patterns on each rotation completion
- 💣 Bomb — visible fuse charges up, then explodes into a projectile nova
- 🔮 Crystal Ball — spawns temporary orbiting shards (bounded by lifetime, not accumulating)
- 🏓 Ping Pong — long-lived bouncing projectiles that gradually fill the arena
- 🍭 Lollipop — spiraling projectiles that expand outward
- 🖌️ Paintbrush — leaves paint-splat damage zones where ball hits walls
- 🪤 Mouse Trap — periodic trap dropping, builds a minefield
- ⛏️ Pickaxe — wall bounce sends shockwave racing along the wall surface
- 🪅 Piñata — rotation weapon that periodically bursts candy projectiles
- 🎆 Fireworks — arcing rockets that explode into persistent burst zones
- 🪀 Yo-Yo — throw, orbit, catch cycle
- ✂️ Scissors — mode switch (snipping melee close, thrown blade far)
- 🪁 Kite — speed-triggered projectile bursts from kinetic energy
- 🎈 Balloon — inflates per wall bounce, pops into nova at threshold
Existing todo weapons kept/reshaped: 🔦 🪃 🪨 💿 🥄 ✏️ ⛓️ 🔔, plus 🔨 reimagined as a slam instead of pure rotation.

NeoVim exited cleanly (empty output is normal for a GUI process). The doc should still be open from the second launch. Let me know what you think of the weapon concepts — happy to dig deeper into any of them.

Same — NeoVim exited cleanly with no console output. The document is updated and ready for review whenever you're ready to look at it.
OK, now let's clean up the todo and remove the weapons as they are designed. Move them to this design file, but note in the file that they are older designs that don't take into account these new ideas.

Now let me read the end of the design file to know where to append the old designs.
Read (E:\a327ex\emoji-ball-battles\reference\attack-design-space.md)
380→
381→### D. Placed / Persistent Effects
382→
383→**🖌️ Paintbrush — Wall-Impact Zones**
384→*Zone + Reactive + Wall-Contact*
385→Each time the ball hits a wall, a paint splat appears at the impact point — a small circular damage zone. Scaling: +zone duration per hit (splats last longer, more accumulate). Visually: the arena borders gradually fill with colorful overlapping paint splats. Over time the walls become "painted" with danger zones. Unique because it weaponizes the ball's bouncing itself — more energetic bouncing means more paint on the walls. Strong visual identity: the arena literally gets more colorful as the fight progresses.
386→
387→**✏️ Pencil — Movement Trail**
388→*Trail + Continuous + Movement*
389→Already in the todo. The ball's trajectory becomes a damaging line. Scaling: +trail duration per hit. Visually: the arena fills with the ball's drawn path, creating complex geometric patterns from bouncing.
390→
391→**🪤 Mouse Trap — Minefield**
392→*Trap + Periodic + Timer*
393→Periodically drops a trap at the ball's current position. Traps arm after a short delay (visual: trap opens), then snap when the enemy ball passes over them. Scaling: +trap active count per hit (shorter cooldown, more traps coexist). Visually: the arena floor fills with tiny open traps that SNAP shut with a satisfying visual when triggered. The accumulation of dormant traps across the arena is the visual escalation — you can see the minefield growing.
394→
395→**⛏️ Pickaxe — Wall Surge**
396→*Wall Effect + Reactive + Wall-Contact*
397→When the ball hits a wall, the pickaxe strike sends a shockwave racing along the wall surface in both directions from the impact point. The surge damages anything it passes (including the enemy ball if it's near that wall). Scaling: +surge travel distance per hit (starts short, eventually races along the full wall length and around corners). Visually: bright streaks racing along the arena borders, like cracks of energy through stone. Uses the arena geometry itself as the attack's shape — totally unique to a bouncy-box game.
398→
399→### E. Hybrid / Unusual Combinations
400→
401→**🪅 Piñata — Spin-and-Fling**
402→*Rotation + Periodic Burst + Rotation-Completion*
403→Rotates continuously like a dagger (contact damage from the piñata itself), but every N rotations it bursts, scattering candy/confetti projectiles in all directions tangentially. Then it "reforms" and keeps spinning. Scaling: +candy per burst per hit. Visually: a spinning piñata that periodically EXPLODES with colorful projectiles scattering outward, then reconstitutes. Combines melee rotation presence with periodic ranged bursts. The cheerful chaos of candy flying everywhere is a strong visual identity.
404→
405→**🔔 Bell — Resonance Pulse**
406→*Charge + Ring + Accumulation*
407→Already in the todo as resonance stacks, but the SHAPE of the payoff should be an expanding ring rather than flat damage. Each hit on the enemy builds visible resonance (the bell glows brighter, vibrates more). At threshold: a large expanding ring shockwave. Scaling: +ring size per hit, or lower threshold (more frequent rings). Visually: the buildup of glowing/vibrating energy, then a dramatic ring burst — a visual exclamation mark.
408→
409→**⛓️ Chain — Tether Weapon**

Good, I have the full picture. Now I'll:
- Append the old weapon designs to the design file under a clearly labeled archival section
- Strip the weapon blocks from todo.md, keeping the non-weapon sections

28→- Spellblade class:
29→ - PASSIVE: swaps weapons periodically between dagger and staff/wand
30→ - Dagger deals physical damage, all physical damage applies Ethereal stacks but deals 0 damage. First magical damage with wand pops ethereal stacks and makes target ethereal for [stacks] seconds.

Done. All weapon designs (Blocks 1–13 plus the status effect system infrastructure) have been moved to reference/attack-design-space.md under a new "Appendix: Original Weapon Designs (Pre-Redesign)" section with a note that they predate the visual scaling framework. The todo now just has a pointer to the design file, plus the remaining non-weapon sections (Other Systems, Classes, Ideas).
OK, now let's create a reference matrix or table of sorts that includes all elements for creating new attacks. Place this file at the top level folder, where main.yue is.

Created ATTACK_REFERENCE.md next to main.yue. It has:
- 4 building block tables — Shapes (19), Behaviors (9), Triggers (8), Scaling (8) — each with an ID code for quick cross-referencing
- Implemented weapons table — the 4 current weapons mapped to the framework (with a note that sword's scaling is the weakest visually)
- New weapon concepts table — all 26 new weapons from the design exploration, each mapped to Shape/Behavior/Trigger/Scaling columns
- Design checklist — 6 questions to verify against when creating any new weapon
Actually, move this file to the docs folder.
