What it does.

Shatterspleen
Boss item (yellow)

Your crits cause bleeding, and enemies that die bleeding explode and hurt the ones around them. Each extra one, a stronger explosion.

Game text: «Critical Strikes bleed enemies for 240% base damage. Bleeding enemies explode on death for 400% (+400% per stack) damage, plus an additional 15% (+15% per stack) of their maximum health.»

Stacking: Each copy adds the same, no cap.

Watch out: It shares bleed with Tri-Tip Dagger. If the first crit kills, there is no explosion.

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