Magic Contraction

Level: 4
Duration: 5 rounds
Saving Throw: None
Normal: With this utterance of protection, you make your target resilient against magical effects.
The target gains spell resistance equal to 11 + your caster level. As a spell fails to overcome the target’s spell resistance, its visible effect shrinks into nothingness over the course of a few seconds. 
Reverse: A string of complex syllables allows you to enhance the power of an ally’s spells for a short time.
You grant your target the ability to apply the effect of the Empower Spell feat to any spell she casts for the duration of the utterance without increasing the cost.
