Concussion Grenade (Combat)

The explosion is just extra.

Prerequisites: Proficiency with grenades.

Benefit: When you throw a grenade, instead of targeting a square, you can aim for a target hitting its KAC. If you hit, you do bludgeoning damage equal to your Strength modifier and 1/2 the grenades level, rounded down. If you miss, you roll as if you missed with a thrown weapon. In either case, the grenade explodes after it lands.
