Berzerker's Pauldron

The Berzerker's Pauldron is an unlockable Uncommon item introduced in Risk of Rain 2. After the wielder kills three enemies within 1 second, they enter into a frenzy for 6 seconds. During this frenzy their attack speed increases by 100% and their movement speed by 40%. The duration goes up by 4 seconds for each subsequent stack.

The easiest way to kill multiple enemies at once is to weaken a group of at least three first, then use an ability that can hit them all.

Completing the Glorious Battle Challenge unlocks this item.
