Items
All 72 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.

Active items
Actives live in their own slot (separate from the passive tray) and are charged by clearing rooms: +1 charge per combat room, +2 per boss. Using an active spends all charges. Picking up a new active drops the old one with its remaining charges. Sources: 30% chance of a bonus pedestal on boss kills, 15% in item rooms. Use with SPACE.
| Active | Cost | Effect |
|---|---|---|
| Bone Nova | 2 | Damage ring + hard knockback around you |
| Offal Bomb | 1 | Lobs a gore bomb at the cursor |
| Blood Transfusion | 2 | Heal 2 hearts, lose 25% of current XP |
| Cleaver Storm | 2 | 12 orbiting cleavers shred on contact for 6 s |
| Butcher's Bell | 2 | Pull every enemy in and stun for 1 s |
| Marrow Draught | 3 | +100% fire rate and free ammo for 5 s |
| Slaughter Time | 3 | All enemies slowed to 25% speed for 5 s |
| Panic Room | 3 | 2.5 s invulnerable — but you can't fire |
| Skinner's Coin | 3 | Clear every enemy bullet into XP gems |
| Gut Reroll | 1 | Reroll the item pedestal you're standing on |
Holding an active contributes a flat +2 to power score.
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.
