Fuiria's solar blessing stops on allies this means that you want to make sure your not too close because it still does damage avoid the beam and focus cauterize on the target or kill furis to keep her from using it again.
Furia is a high damage healer mostly for her pyre strike. this can seal kills and stop flankers in their tracks but it takes a long time to spawn just attacking her can bait her to use it and juke her out and seal the kill.
Vivian's shield can be annoying for all characters but Pip can shoot next her or on a wall behind her to do splash damage to seal the kill if she is low health when she spawn it.
