The Bomb! is an item in ActRaiser.
Description[]
It is an item offered up by villagers, usually after purging a Monster Lair. It will annihilate all visible monsters in Sim Mode, but not their lairs. It's useful for a quick reprieve from their attacks, or as a "panic button" in case the Angel can't quite make it to an enemy in time, such as a Skull Head right before it causes an earthquake.
Not to be confused with the Crush, which only appears in Act Mode.
