This spell inflicts damage, and then either ends the caster's turn, or returns its casting cost.
This spell is effective for using up the 2 AP that you are often left with after using weapons, esp. a sword if the enemy is in melee range.
With God Ecaflip this spell costs nothing, but can still only be used 4 times. If your isn't ended then, you get 2 AP more than you had before you cast it.
