Dimensional Seal (Su)

The arcanist can expend 1 point from her arcane reservoir to emanate a field centered on herself which blocks dimensional travel—including summoning and teleportation effects, as well as the dimensional slide exploit—in a radius of 5 feet per arcanist level for a number of minutes equal to her Charisma modifier (minimum 1). She may dismiss this effect at will. The arcanist must have the dimensional slide exploit to select this greater exploit.
