Captain H'bri

Captain H'Bri is linked with her Lieutenant. These mobs MUST be tanked in separate rooms or they will gain multiple damage shields and will be impossible to kill.

When you enter the room, head to the right and take the portal to a different room. Clear all the golems. Once the golems are dead, split the raid as you see fit to have some in the golem room and some in the Captain's room. When you pull the Captain she will emote and tell the Lieutenant to check the golem room for invaders and the Lieutenant will respawn in that room. Once you engage, you will no longer be able to use the portal until the Lieutenant is dead, so make sure everybody is in position and ready to go.

Kill the Lieutenant. Once he is dead, use the portal to return to the Captain's room and kill her.
