Brainstalks

The Brainstalks is an unlockable Rare item in Risk of Rain 2.

After the player kills an elite enemy, all their abilities lose cooldowns for 3 seconds, with each subsequent stack adding 2 seconds to the effect. This means they can be activated repeatedly as long as the character is not in the middle of preforming another, uninterruptible one, such as Eviscerate.

Completing the Challenge Deicide unlocks this item.
