Here are some pvp centered armor set ideas. These are the finale 5 piece set abilities.
1. When hit with vicious death; all vicious damage goes back on player wearing vicious death armor.
2. When killed by a player all their HOTs are turned into oblivion damage until you are rezzed
3. When a negate is dropped on enemy players, any wearing a mythic armor piece is frozen in place for 2 seconds
