Rending the Shroud (Su)

Benefit: Whenever the magus makes a successful melee attack, she may spend 1 point from her arcane pool as a swift action to reduce her target’s spell resistance with no save allowed. The target’s spell resistance is reduced by the magus’s Intelligence modifier for a number of rounds equal to ½ her magus level. Multiple uses of rending the shroud do not lower the target’s spell resistance further, but do reset the duration to ½ the magus’s level.
