Magebane Attack

Prerequisites: Advanced Rogue Talents.

Benefit: Through a combination of pain and distraction, a rogue with this talent can make it hard for spellcasters she hits to use their magic. For one round after the rogue deals sneak attack damage to an enemy, that enemy must make a concentration check or lose any spell or spell-like ability it attempts to cast. The DC of the concentration check is equal to 10 + the spell’s level + twice the number of sneak attack dice the rogue possesses.
