GRAIN ROT tips verified August 16, 2026.
Treat the Elevator as the run’s exit plan, not just the way down.
A broken Vessel puts you into Spark mode; use the state to scout and re-host.
The deeper layers increase Rot pressure, so take a safe extract when your haul matters.
The Grinder turns suitable finds into gold; treat conversion timing carefully and verify any attention risk in-game.
Confirm exact symbols, enemy behavior, and upgrade costs in-game or with the community before committing a run.
