Mystic Rampart

Level: 6
Duration: 5 rounds
Saving Throw: None
Normal: With a complex string of syllables, an intangible tower superimposes itself over your ally, greatly enhancing his ability to protect himself. 
You grant your target damage reduction 5/— and a +5 bonus on saving throws as your utterance superimposes a ghostly tower or castle over his form. The tower is just barely visible and doesn’t obscure or conceal anything behind it. 
Reverse: You speak and your target becomes vulnerable. The reversed utterance superimposes a crumbling, ruined tower over your target, which takes a –5 penalty to Armor Class and on saving throws for the utterance of the duration.
