Summoning Grenade IV

Grenade

The explosion a summoning grenade generates is a reality-warping field that summons creatures as if you had cast a 4th level summon creature spell with a caster level of 12. The creatures to be summoned are set when the grenade is created, so you know what you're getting when you buy, presupposing a scrupulous vendor. When the grenade detonates, the summoned creatures appear immediately in unoccupied spaces, but a creature needs to have only 1 square of its space inside the blast radius. If a creature doesn't have enough room to appear, it doesn't. Summoned creatures treat you as their summoner.
