At 1st level, once per day, the arcane trickster can dispel a magical effect on a target and receive statistical bonuses from it. The ability is a touch attack "lesser" dispel that affects the most powerful effect currently on the target. If successful, the effect vanishes from the target and the arcane trickster receives +2 bonus to attack rolls and all saving throws for the next ten rounds. He can use this ability twice per day at 5th level and three times per day at 9th level.
