Spellcaster's Stance [Level 1]

You gain an arcane caster level equal to your initiator level. You gain spells per day as a wizard of a class level equal to your arcane caster level. Choose a number of spells equal to the number of maneuvers you know, of a level not higher than the highest level maneuver you know. These are treated as being in your spellbook. You may change these spells every time you enter the Spellcaster's Stance.

There. Simple.
