Grenade, Fuse
Source Adventurer’s Armory
This hollow clay container holds a small charge of explosive power and a slow burning fuse. Lighting the fuse is a move action; 1d3 rounds later the grenade explodes, dealing 2d6 bludgeoning damage and 1d6 fire damage in a 10-foot burst (DC 15 Reflex save for half ). You throw a fuse grenade as if it were a splash weapon.
