Im helping a friend do arah path 4 and corrupted high priest of Dwayna is giving us trouble we have tried over 4 different ways to kill her and nothing seems to work anymore. Each time she gets to 50% shes goes invisible and heals nothing we can do to stop it if we get the sparks in the marks fast enough she will become visible again but then will go invisible once she reaches 50% have been trying different ways for over 2 hours now
