This strategy is written for World of Warcraft: The Burning Crusade (TBC 2.4.3), the Black Temple raid for 25 players. Mechanics and numbers match the fight on the Moonwell server.
A 25-player fight; you need 3 tanks. Shadow beams hit the raid for the whole fight. The main danger: Fatal Attraction if the linked players don't scatter, and Saber Lash on a single tank.
Saber Lash
85% chance on a hit, no more than once every 9 sec: 76,000–84,000 physical damage split evenly among three targets in a 20 yd cone in front of her. Three tanks stand right in front of her. Every 5 sec, Saber Lash marks these three: 20 sec with no knock-up and no Fatal Attraction.
Beams
At 15 sec, then every 27 sec, she picks a new beam and fires it three times, every 9 sec. A beam hits a random player and jumps to others within 25 yd, up to 10 targets in total. Sinful Beam: 6,938–8,062 Shadow damage. Sinister Beam: 2,000 and a strong knock-up. Vile Beam: 2,500 every 2 sec for 8 sec. Wicked Beam: burns 1,000 mana, and the damage is four times that. Prayer of Shadow Protection helps.
Fatal Attraction
At 22–29 sec, then every 22–40 sec. Three random players, other than those marked by Saber Lash, are teleported to one spot in the room. Every second, while another linked player is within 25 yd, each of them hits everyone within 15 yd, themselves included: 750, 1,500, 2,250, then 3,000 Shadow damage each time. Three together means up to 9,000 per second each. Run in different directions at once, and not toward the raid. Beyond 25 yd from the other linked players, the link drops.
Aura and shriek
Every 15 sec, Prismatic Aura: Shadow or one of five others: players' damage of one school −25%, the opposite school +25%. Pairs: Shadow and Holy, Fire and Frost, Nature and Arcane. Silencing Shriek at 16 sec, then every 16–25 sec: a 10 sec silence on everyone within 18 yd of her. Healers and casters stand farther away.
10% and the timer
Below 10%, a random beam fires every 6 sec, and every 20–30 sec comes Enrage: +75% physical damage and attack speed for 10 sec, and Saber Lash hits harder too. Tanks save defensive cooldowns for this time. Berserk at 10 min: +500% damage.
Tanks
Taunt doesn't work. The main tank builds threat first, and the other two stand on him. Don't turn the boss.
Healers
Keep the raid topped off before the beams. A dedicated healer heals the linked players with instant spells.
DPS
Melee stand behind her. Casters use their abilities when the aura boosts their school.
Common mistakes
- The linked players run together or through the raid: the damage hits everyone within 15 yd.
- The other two tanks are not next to the main tank: he takes the whole Saber Lash.
- A DPS stood in front of the boss and took a share of the hit.
