In-game pickup line
“Cursed?”
Mechanics
What Guppy's Tail does
- A room clear has a chance to replace its normal reward with a chest.
- Another portion of clears gives no reward, so the effect is a tradeoff rather than a guaranteed extra drop.
In a run
Practical note
Keep enough keys to benefit from the extra chests it can generate.
