Grenades

Grenades are thrown weapons that detonate in an explosive radius when they reach the target. A grenade’s listing on Table 7–7: Grenades shows its explosion radius. Some grenades have additional effects, such as blinded or entangled, that apply only to creatures in the explosion radius that fail a Reflex save against the grenade. The DC of the save is equal to 10 + half the grenade’s item level + your Dexterity modifier. Any penalty you take to your attack roll also applies to this save DC.
