Molten Perforator
Boss item (yellow)

10% of your hits pull 3 lava balls out of the enemy that set things on fire. Each extra one, more damage.

Game text: «10% chance on hit to call forth 3 magma balls from an enemy, dealing 300% (+300% per stack) damage and igniting all enemies.»

Stacking: Each copy adds the same, no cap.

Watch out: It deals 300% of the hit, not of base damage (the game is wrong). Misses small enemies; great on big ones and bosses.

It has a void version: Newly Hatched Zoea. Pick that up and every copy of this item turns into it.
