Earthquake

Earthquake inflicts damage to everyone on the map, including the caster! It doesn't do a lot of damage, but it can help wear down a mob of low level varmints. It has a low AP cost, so it's a fun spell to cast in addition to another spell. Be warned: the Earthquake will hurt your dollies (and your allies and their summons.)

Sneaky trick: The Earthquake inflicts damage at the start of the character's turn. If you've gotten all but the last one or two of an enemy's hit points and you still have two AP left, cast Earthquake to finish them off. You'll have to wait until they take their turn to see their demise, but you've effectively eliminated them from the fight.
