When you cast this spell, you designate a target composed of one of the four elements—earth, fire, air, water.
The target then releases magical energy in a sudden, explosive burst, as follows:

Earth: The target throws off sharp slivers and fragments; creatures within the burst take 1d8 points of damage (Reflex save for half damage).


Fire: The target shoots out glowing sparks that deal 1d8 points of fire damage to creatures within the burst (Reflex save for half damage).


Air

Water:Water pushes out in a fierce wave, knocking creatures within the area prone unless they make successful Reflex saves.
Creatures get a +4 bonus on their saving throws for each size category they are larger than Medium, or a -4 penalty for each size category smaller than Medium.
Exceptionally stable creatures, such as dwarves or creatures with four legs, get an additional +4 bonus.
The spell does not noticeably affect the structure or form of the target object.
