GRAIN ROT Elevator Modifiers: Shop Cube, Fuse, Map Room & Trap

What Elevator Modifiers Are

Before each descent, the elevator panel flashes a set of modifier symbols — procedural run conditions that reshape loot placement, hazards and optional objectives for that floor. You can't pick them; you read them, adapt, or decline the depth. Modifiers stack — a Shop Cube run can also demand a Fuse — and the general rule is that more reward symbols pair with more Corrupted pressure.

Confirmed Modifiers

▸Shop Cube

Shop items scatter across the map in seed-fixed spots — benches, lockers, alcoves. Documented finds include guns, bats, healing bottles, compasses and mallets (wooden swords are reported but not universally confirmed). Free gear reduces Grinder dependency.

• Assign a scout to sweep side rooms early — never skip shop rooms during this modifier
• Synergy: with Map Room active, weapons may appear on the map room's interior bench

▸Fuse

The elevator halts until the crew finds and installs a fuse.

1. Icon triggers on landing — descent is locked
2. Search lockers and boxes; fuses have multiple spawn points
3. Slot the fuse into the elevator to resume

• Compass shortcut: a compass can substitute for a fuse — trading your navigation tool to skip the search (community-confirmed)
• Team shape: two search, one anchors near the elevator, one flexes for Corrupted contact
• Synergy: with Map Room active, fuses sometimes spawn in the map table box

▸Map Room

A dedicated chamber spawns containing a table map with live ally positions, plus ambient props — a fan, a gramophone, a telephone — and a breakable lantern. Standing in the lantern's fire burns Rot off your vessel gradually, at the cost of vessel damage.

• Call its location early: it reunites crews split by Grinder noise events
• The lantern is a field Rot cure when you can't reach the surface scorch — pricey, but it can save a run

▸Trap / Bear Trap

Environmental floor hazards — bear traps or similar triggers — spawn in corridors. Movement discipline outweighs combat stats:

• Scout slowly; never sprint blind into narrow halls
• The flex player carries healing if Shop Cube rolled bottles
• Traps funnel greedy routing into Corrupted spawns — extract earlier than usual

Community-Reported (Unverified) Modifiers

These circulate from demo footage but aren't confirmed in the launch build: lights-out (reduced visibility) and increased gold / enemy count variants. Treat them as real until patched otherwise — the rule of thumb holds either way: more reward, more pressure.

Pre-Descent Modifier Checklist

1. Call every symbol aloud in voice chat
2. Assign a fuse hunter if the Fuse icon shows
3. Note Shop Cube and prioritize side-room sweeps
4. Set an abort rule if Trap plus a deep push exceeds crew skill
5. Confirm everyone is Rot-free before boarding — symptoms in transit can destroy Outpost rooms
