4 Horsemen Base Abilities

1. Summon Spirit - when each horsemen dies their spirit is summoned out, stays in their respective corner and keeps stacking marks. Do not go near them, they can kill melee in one hit.
2. Shield Wall - This is done at 50% and 20% health and lasts 20 seconds.
3. Enrage - after 100 marks are cast the horsemen will enrage, allowing the use of their abilities with no cooldown.

Thane Korth'azz Specific Abilities

Sir Zeliek Abilities

2. Holy Wrath is chain holy damage, jumping between players that are within 5 yards of each other. Everytime it jumps to another raid member the damage is doubled.

Strategy

1. Place each boss in different corners. Thane Korth'azz should be in the front left, Baron Rivendare in the front right, Lady Blaumeux should be in the back left, and Sir Zeliek in the back right.
2. After three Marks stack the groups need to rotate to the direct opposite corner. This is done so the raid does not wipe because of the marks stacking and allow the current mark to expire.
3. Sir Zeliek and Lady Blaumeux deal magical damage and can be tanked by a Warlock or Death Knight.
