Counterspell

Associated School: Abjuration.

Replacement Powers: The following school powers replace the protective ward power and the energy absorption power of the abjuration school.

Disruption (Su): At 1st level, you gain the ability to disrupt spellcasting with a touch. As a melee touch attack, you can place a disruptive field around the target. While the field is in place, the target must make a concentration check to cast any spell or to use a spell-like ability in addition to any other required concentration checks. The DC of this check is equal to 15 + twice the spell’s level. If the check is failed, the target’s spell is wasted. This field lasts for a number of rounds equal to 1/2 your wizard level (minimum 1). You can use this ability a number of times per day equal to 3 + your Intelligence modifier.

Counterspell Mastery (Su): At 6th level, you gain Improved Counterspell as a bonus feat. You may attempt to counterspell an opponent’s spell once per day as an immediate action (instead of a readied action). You must use a spell at least one level higher than the spell being countered to use this ability. You can use this ability once per day at 6th level, plus one additional time per day for every 4 levels beyond 6th.
