due to BR (bomber royal) appearing in trove the pvp in the game has become glitched temporaily, example if you switch class in pvp, you will lose all ability & powerup will stack if you get more then one of the same kind if not will work as intended & lastly if you used a class that have no er (energy regen) at start and swap to another class the other classes you swap to become unable to regen er and stat stay the same as boomer (boomeranger) or revenant.
