Benefit: The magus can spend 1 point from her arcane pool as a swift action to channel arcane energy through her weapon, which allows the power to flow into her opponent and disrupt his magical defenses. As a free action before resolving an attack, she may declare that she is using this ability. If she hits, roll and apply damage as normal. In addition, if the target fails a Will Save (DC 10 + half her magus class level + her Intelligence Modifier) the target’s spell resistance, energy resistance, or damage reduction is reduced by her magus class level for a number of rounds equal to her magus class level.

Special: A creature or object that saves against this ability is immune to the effects of her resistant strike for 24 hours.
