Blood and Ice
Shirt of Repulsion
Any enemy that attempts to move into your space, or a space adjacent to you must succeed a DC 20 strength check, or be knocked back. They are pushed into the square directly behind them. If there is an obstacle between the thrown back creature and the space directly behind them, they take 1d6 bludgeoning damage each round they remain near you until they succeed a strength check or move to the side. Any enemy who makes the DC must make a strength check every round he or she remains near the wearer of the shirt.
Often employed by celebrities, the shirt of repulsion throws back any creature or person you designate, or who means you direct harm.
