Mimic Chest
Disguises itself as a brown chest, then reveals spikes when Isaac gets close.
Value / opening ruleBecomes spiked when approached
How it works
- After changing, it normally costs half a heart to open and has ordinary Chest rewards.
- Flat File prevents the conversion into a Spiked Chest.
Before you collect
Approaching it can turn an apparently free chest into a health payment.
Recognize the chest


Original game frames. Mimic and Haunted Chests resemble an ordinary chest before their behavior reveals the hazard.
