Strategy & Tactics Guide - Blood Queen Lana'Thel

Blood Queen Lana'thel: Feeding the teenage vampire craze.
Hotter than Lestat and better than Twilight saga. She is also the wing boss of the Crimson Halls, giving your raid a limited number of attempts to defeat her.
This is a simple two-phase encounter that nonetheless can go very wrong very quickly. It's also rather intensive on the healing and cannot be done while watching Top Gear on the telly due to attention check mechanics.
Throughout the fight you will suffer from an aura of sorrow, dealing 4.5k shadow damage every 2 seconds. This damage is increased by 5% per vampyr in the raid (more on that later).
To start things off your two tanks shoud stand on top of each other and use taunts to avoid Delirious Slash, a stacking ~5k DoT, getting too high.
You should also be spread 6 yards apart to avoid splash damage from her Bloodbolt on a random target.

The key ability of the fight is the Essence of the Bloodqueen.
This debuff inflicts ~13k damage on a random person and increases their damage by 100%. Attacks will cause no threat for the 60 second duration.
After 60 seconds have elapsed they will thirst for blood, and must bite another player within a 15-second window or they will lose control of their characters and go into a frenzy. Biting someone spreads the Essence of the Bloodqueen to someone else as well as refreshing it on the original receiver.
You want to avoid biting someone as long as possible (without risking the mind control) to keep the number of vampyrs in the raid low, due to the 5% increase to the raid-wide shadow aura, and so you don't run out of people to bite. This also places a soft enrage on the fight so you need solid DPS, even before the 100% damage buff from the Essence. It helps if you arrange your ranged so they're next to each other, as the Bite can only be used in melee range.
Lastly Black Temple raiders will be familiar with the last two abilities.
The Pact of the Darkfallen will link three players together with large red beams, causing them to deal lot of damage to other players. Hello Mother Shahraz. They must quickly run together to unlink themselves. She casts this at random throughout the fight and is just a basic execution check, though it only takes the one person messing up to set the failboat in motion.

The other ability is a simple Legion Flame-type debuff, causing the player to put down shadow flames under their feet every second for 6 seconds. They will need swift heals and must also move so they don't damage other people.

After about two minutes of this she will take to the air. If you were already spread out then simply heal through this high-damage phase. Melee and tanks get a few seconds to spread further apart before the Blood Whirls start hitting the raid.In 25-man she also does a short fear when she takes off so you should spread out when she leaps to the center of the room. Tremor totems, PvP trinkets, racials and similar abilities work.
