Blood-Queen Lana’thel Boss Fight Tactics

The most important thing to remember about the fight against Blood-Queen Lana’thel is the biting. She bites a random raid member early on in the battle. Then after about a minute, that raid member must bite another raid member, or he will become mind-controlled. The biting is important because it increases the amount of damage you do by 100 percent. Therefore, the first one you should bite is your top DPS. When that raid member needs to bite someone, he should bite the next highest DPS, and so forth. Healers and tanks should only be bitten after all the DPS members have already been bitten. You want your highest damage dealers doing the most damage possible, because you’ll wipe the entire raid if you don’t kill Blood Queen Lana’thel before you run out of raid members to bite. Each raid member can only be bitten once.
Keep your ranged DPS and healers spread out evenly to avoid the abilities that damage nearby raid members in addition to the target raid member.
Healers, pay attention to which raid members have Blood Mirror cast on them. You must heal through this ability because you could end up with a squishy raid member taking as much damage as the tank. You really can’t afford to lose any raid members during this battle.
If a circle appears under you, just keep moving to stay out of it. All nearby raid members should also move to stay out of it. Swarming Shadows will kill you if you keep standing in.
If Pact of the Darkfallen is cast on you, look for the other raid members you’re linked to. A red line will connect all the linked players. Linked raid members must run together and meet to get rid of Pact of the Darkfallen.
Healers, prepare for the aerial part of the battle after the ground part. All raid members will be hit with Bloodbolt Whirl during the aerial part, so be prepared for heavy healing.
