In-game pickup line
“Extra life”
Mechanics
What 1up! does
- If Isaac dies, the extra life revives him once instead of ending the run.
- The revive restores health, though its exact amount can depend on the character's health rules.
In a run
Practical note
Treat it as insurance for a difficult route, not as protection against the hit you are about to take.
