Daily
Target: 
You or one nearby ally
Effect: 

For the rest of the battle (or for five minutes), the target gains resist damage 16+. Enemies who can see invisible creatures ignore this resistance.

Whenever the target uses a move action, there is a 50% chance that it can teleport somewhere nearby instead of physically moving.

9th Level Spell: 
75% chance.
