Kjaro's Band
Uncommon item (green)
When you land a very big hit (over 4 times your damage), a fire tornado also comes out. Once every 10 s. Each extra band, more damage.
Game text: «Hits that deal more than 400% damage also blasts enemies with a runic flame tornado, dealing 300% (+300% per stack) TOTAL damage over time. Recharges every 10 seconds.»
Stacking: Each copy adds the same, no cap.
Watch out: The hit itself must deal 400%: crits and Armor-Piercing Rounds do not count. It always fires with Runald's and they share the cooldown.
It has a void version: Singularity Band. Pick that up and every copy of this item turns into it.
