The Impossible Robe

The wearer of this robe exists between several realities at once. Thus can a daemonic commander potentially control Tzeentch's interests in multiple times and places simultaneously to further multiple aspects of the Great Plan. This effect makes it hard for foes to truly harm the wearer, who flickers between planes of reality in an unpredictable fashion. However, the robe is capricious, and has been known to rip its wearer out of reality altogether should they lose control of its powers.
