GABAL'S SCHOOL OF WAR
Student of War
You have studied the art of war at Gabal’s wizard’s school, and have practiced battling many foes at once.
Benefit: You gain Knowledge (history) as a bonus class skill. Additionally, you can strengthen your spells for use in large-scale battles. You can spontaneously modify a spell, which extends its casting time: if the spell’s normal casting time is 1 action, casting the modified version is a full round action; for a spell with a longer casting time, it takes and extra full round action to cast the modifies version. When you do so, if the modified spell affects three or more creatures, increase the spell’s save DC by +1.
