Improved Sneaky Familiar

Your familiar has learned even more from your stealth and tricks in combat.

Prerequisite(s): Arcane bond (familiar) and impromptu sneak attack class features, sneak attack +3d6, Sneaky Familiar

Benefit: Your familiar gains an additional +2 bonus to Stealth checks. In addition, when you make an impromptu sneak attack, the next time your familiar attacks the target, the target loses its Dexterity bonus to AC against your familiar's attack. This benefit only applies if the familiar attacks the target within a number of rounds equal to your level in arcane trickster.
