What it does.

Brilliant Behemoth
Legendary item (red)

All your attacks explode and hurt nearby enemies. Turns any attack into an area attack. Each extra one, a bigger explosion.

Game text: «All your attacks explode in a 4m (+1.5m per stack) radius for a bonus 60% TOTAL damage to nearby enemies.»

Stacking: Each copy makes the blast bigger; damage does not go up.

Watch out: The blast copies the hit: if Lost Seer's Lenses instantly kill something, the blast can also kill a boss standing next to it.
