"Mine is actually better than Gandalf's in a few ways."
A 3 Gift Push / Pull Power used by Preston Vincent Astor III, created by ShadyTradesman.
Preston withdraws his staff, spins it above his head and shouts "YOU SHALL NOT PASS!" before driving it into the ground. A visible shockwave eminates from the point of contact, and all creatures he determines are ejected from the area and cannot approach. He may move slowly with the staff or leave it in position.
Exert your Mind, choose an Animate target, and roll Charisma + Occult6 as a Committed Action, which the target can resist by rolling Mind, Difficulty 6 as a Free Action. Success prevents the target from approaching within 45 feet of you for 1 Minute. A tie cuts the target's move speed in half while moving towards you within 45 feet for the same amount of time. Difficulty
This Power requires continuous Concentration to maintain. You may only move at walking speed while concentrating, and any significant interruption (such as taking damage or being grappled) will break the effect.
