Repelling Ward

Evocation [Ward]
Circle: Shaman 3
Casting Time: 1 standard action
Range: 0 ft
Effect: Aura of protective energy
Duration: [Encounter]
Saving Throw: Will and Fortitude negates; see text

You create a spread with a radius of your [Close] range originating from you, which moves with you and lasts until the end of the [Encounter]. Whenever an opponent outside the spread attempts to enter the spread, it is unable to enter. A successful Will save negates this effect and allows the opponent to enter the spread as normal for the rest of the [Encounter]. For each opponent, the first time each [Encounter] that opponent chooses to enter a square within the spread, it becomes [Nauseated] for one [Round]. A successful Fortitude save negates the [Nauseated] condition.
