Runald's Band
Uncommon item (green)
When you land a very big hit (over 4 times your damage), an ice blast also hits that slows enemies a lot. Once every 10 s. Each extra band, more damage and a longer slow.
Game text: «Hits that deal more than 400% damage also blasts enemies with a runic ice blast, slowing them by 80% for 3s (+3s per stack) and dealing 250% (+250% per stack) TOTAL damage. 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 Kjaro'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.
