The Stun Grenade is a new item in Risk of Rain 2. It gives every shot a chance to stun any non-boss enemy, interrupting most attacks and locking the enemy in place for a few seconds. It is one of the only items in the game with Hyperbolic Stacking, meaning that as the player collects more the item adds less and less chance to stun. The chance to stun is also multiplied by the Proc Coefficient.

Math[edit | edit source]

The chance to activate is determined by the formula 1 - 1 / (1 + 0.05 * amount)
