Levitate (3rd Level Utility)

Ranged spell
Daily
Effect: 

Until the end of the battle, you can use a move action to rise straight up into the air or descend straight down. The spell itself won't move you horizontally. The up-or-down movement is about half as fast as your normal movement. While levitating, you take a –2 penalty to your attacks and are vulnerable to attacks against you.

5th Level Spell: 
You can now cast the spell on a nearby willing ally instead of yourself.
7th Level Spell: 
You can now cast the spell as a quick action, and the spell can now affect two targets.
9th Level Spell: 
The spell can now affect five targets.
