- Add ITEM_RARITY (common/uncommon/rare/legendary) with per-item tier caps - Weighted pools per source: elites favour common, item rooms uncommon, bosses rare/legendary; legendaries are boss-exclusive; capped items excluded - Rarity-weighted powerScore so deep common stacks inflate difficulty less - Differentiate duplicates: Grafted Trigger, Crow Bait, Hollow Bones, Twin Hearts - 14 new clean passives incl. Chill Gland (activates slowOnHit) and Hooked Sinew (activates magnetPull); revive magnetPull in pickups - Rarity-tinted pedestal glow + nameplates, rarity-sorted HUD implant tray, dynamic help implant pages (8 -> 9) - Generate 14 item icons via gen_assets.py; bump asset cache to v=38 - Update smoke tests for 60 items, per-item caps, pools, weighted power

# Items
|
||
|
||
All **60 passive items** in MeatSlicer, with exact effects pulled from `js/items.js` and the proc logic in `js/enemies.js` / `js/player.js`.
|
||
|
||
---
|
||
|
||
## How items work
|
||
|
||
- Items are **passive and permanent** for the run. Pick one up and its effect applies immediately.
|
||
- **Duplicates upgrade the tier** (shown as Roman numerals on the pedestal and in your item tray). Each duplicate re-applies the item's effect — multiplicative stats compound, additive stats stack linearly.
|
||
- **Tier caps are per-item.** Simple stat items stack deep (up to VIII); build-defining and legendary items cap at III or I. Picking up a duplicate at cap instead grants +150 score and 5 XP gems with a "MAX" toast.
|
||
- **Every item has a rarity band** — Common, Uncommon, Rare, or Legendary — which drives both its drop weight and how much it inflates enemy scaling (see below).
|
||
- Item rolls use a "smart roll": a small chance to upgrade an item you already own (below cap), otherwise a weighted roll from the source's pool. Builds naturally specialize, but rares stay rare.
|
||
|
||
### Rarity bands
|
||
|
||
| Band | Base weight | Power/tier | Typical cap | Colour |
|
||
|---|---|---|---|---|
|
||
| Common | 100 | 0.5 | V–VIII | bone |
|
||
| Uncommon | 55 | 1.0 | IV–VI | teal |
|
||
| Rare | 25 | 1.5 | II–III | gold |
|
||
| Legendary | 8 | 3.0 | I | red |
|
||
|
||
**Power score** (drives enemy HP/speed scaling) = perks × 0.5 + Σ(item tier × band power). A deep stack of commons inflates difficulty far less than a few rares.
|
||
|
||
### Where items come from
|
||
|
||
| Source | Chance | Pool tilt |
|
||
|---|---|---|
|
||
| Item room pedestal | Guaranteed (1 per floor) | Favours Uncommon / Rare |
|
||
| Boss kill | Guaranteed (1 pedestal) | Favours Rare / **Legendary** (boss-only) |
|
||
| Elite enemy kill | 18% + luck × 10% | Favours Common |
|
||
|
||
Legendary items are **boss-exclusive** — they never roll from item rooms or elites. Items already at their tier cap are excluded from fresh rolls, so pedestals don't waste themselves.

||
## Damage & Fire Rate
|
||
|
||
| Item | Description | Effect per tier |
|
||
|---|---|---|
|
||
| **Hollow Points** | +25% damage | `dmgMul ×1.25` |
|
||
| **Marrow Glut** | +20% damage, −10% fire rate | `dmgMul ×1.20`, `rateMul ×0.90` |
|
||
| **Bloat Rounds** | +25% attack size, +10% damage | `sizeMul ×1.25`, `dmgMul ×1.10` |
|
||
| **Twitch Fibers** | +20% fire rate | `rateMul ×1.20` |
|
||
| **Grafted Trigger** | +18% fire rate, +6% shot speed | `rateMul ×1.18`, `shotSpeedMul ×1.06` |
|
||
| **Bonemeal Powder** | +15% damage, +15% shot speed | `dmgMul ×1.15`, `shotSpeedMul ×1.15` |
|
||
| **Marrow Piston** | +30% knockback, +12% attack size | `knockbackMul ×1.30`, `sizeMul ×1.12` |
|
||
| **Whipcord Tendon** | +20% range, +8% fire rate | `rangeMul ×1.20`, `rateMul ×1.08` |
|
||
| **Butcher's Twine** | +12% bleed, +8% fire rate | `bleed +0.12`, `rateMul ×1.08` |
|
||
|
||
Note: attack size (`sizeMul`) also enlarges melee arcs, blast radii, acid pools, and projectile hitboxes — Bloat Rounds is secretly an AoE item.
|
||
|
||
## Shot Modifiers

|---|---|---|
|

|
||
|
||
## On-Hit Procs
|
||
|
||
All of these trigger from your weapon hits (orbital knives proc at half chance). Chances stack additively across tiers and are rolled per hit.
|
||

|
||
| **Chain Sinew** | Hits arc to +1 nearby enemy | `chain +1` — arcs to up to 6 nearby enemies within 180 px for 35% of the hit's damage each |
|
||
| **Mortar Bone** | Every sixth hit erupts | `mortar +1` — every `max(2, 7 − mortar)` hits, AoE blast: radius `42 + mortar × 5`, 55% of the hit's damage |
|
||
|
||

## Synergy notes
|
||
|
||
- **Second Stomach** turns *every* healing source into shield generation: Worm Gut, Bone Knit, Vampire Dentures, Hemophage, and hearts at full HP.
|
||
- **On-hit procs scale with hit frequency** — pair Flayer Kiss / Ember Jar / Chain Sinew with the Ribcage Repeater, Bile Blunderbuss, or Cauterizer.
|
||
- **Split Tongue / Hydra Maw / Backstabber** multiply projectile count, which multiplies proc rolls per second — the core of most broken builds.
|
||
- **Piercing Gaze + Ricochet Ribs** feed the slam/saw/beam "inert" bonus (+6% each) on The Tenderizer, Red Right Hand, and Spinal Tap, while also powering Swarm Jar maggots.
|
||
- **Volatile Bile** chains: explosions can kill, which triggers more explosions (and frenzy, and lifesteal procs).
|
||
- **Bone Plate + Shield Heart** (perk) stack into a large shield that refills free every floor.
