Description: You can use other creatures’ bodies as the source of any spell you cast.

Prerequisites: Enlarge Spell

The character casts a spell at a primary target within the spell’s normal range, but instead of being affected, it becomes the new source of the casting. The character chooses a secondary target, and the spell goes off as if the primary target was the spell’s caster, calculating range and line of effect from that point. The spellcaster must still be able to see the secondary target. A bounced spell uses up a spell slot two levels higher than the spell’s actual level. The visual effect of a fireball ricocheting off an ally into the true intended target can be very impressive.
