Legerdemain

At-will, swift, concentration; you manifest an invisible hand of force in an unoccupied square within 10 squares of you. While you concentrate, you can move the hand up to 6 squares as a move action and use it to perform any Dexterity-based skill check as if you were in its square, using your own skills and bonuses. The hand can lift up to 10 pounds, manipulate objects, open unlocked doors and containers, and pick pockets, but it cannot attack or wield weapons.

A creature that succeeds on a Perception check against your Stealth check notices the hand's activity, but not the hand itself.

At rank 2, the range is 20 squares and the hand can lift 50 pounds. At rank 3, you can manifest two hands with one concentration.
