Grenades

Tossed, opened, or otherwise drawn out casts an associated Attack Evocation at a target or around the thrown spot. General samples:

Hot Spot: flame erupts on spot and immolates a small area (2 base shifts affect the zone where thrown)
Instant Lightning: gulp this down to channel a single bolt of lightning on the poor bloke whom you dislike
