Siegebreaker

A siegebreaker carries 15 alchemical grenades that deal either acid, cold, or fire damage plus 10 persistent damage and 10 splash damage of the same type (typically five of each damage type). They replenish these grenades each day.

When an attacker scores a critical hit against the siegebreaker, one of the siegebreaker's alchemical grenades bursts. The GM determines the grenade randomly. The siegebreaker takes damage from the grenade as though they were hit by the grenade (applying their resistance normally), and any creature in a 10-foot emanation takes the splash damage.

The siegebreaker's grenades deal splash damage in a 10-foot emanation.

The siegebreaker Interacts to draw a grenade, then Strikes with it.

When time's up, the bomb explodes in a concentrated 20-foot burst, dealing 20d6 acid, cold, or fire damage that ignores up to 10 Hardness of structures. Any creature in the area can reduce the damage they take with a DC 37 reflex save.
