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.
