Associated School: Evocation.
Replacement Powers: The following school powers replace the force missile and elemental wall powers of the evocation school.
Versatile Evocation (Su): When you cast an evocation spell that does acid, cold, electricity, or fire damage, you may change the damage dealt to one of the other four energy types. This changes the descriptor of the spell to match the new energy type. Any non-damaging effects remain unchanged unless the new energy type invalidates them (an ice storm that deals fire damage might still provide a penalty on Perception checks due to smoke, but it would not create difficult terrain). Such effects are subject to GM discretion. You can use this ability a number of times per day equal to 3 + your Intelligence modifier.
Elemental Manipulation (Su): At 8th level, you can emit a 30-foot aura that transforms magical energy. Choose an energy type from acid, cold, electricity, and fire, and a second type to transform it into. Any magical source of energy of this type with a caster level equal to or less than your wizard level is altered to the chosen energy type. This includes supernatural effects from creatures with Hit Dice no greater than your caster level. For example, you could transform a white dragon’s frigid breath weapon (a supernatural ability), but not a fire elemental’s fiery touch (an extraordinary ability). If an effect lies only partially within your aura, only the portions within the aura are transformed. You can use this ability for a number of rounds per day equal to your wizard level. The rounds do not need to be consecutive.
