Not a single person should die using this exploit except for maybe the main tank if he doesn't get enough heals
The tank goes after the troll while the rest of the party runs up the pyramid. Half way up the stairs, there is a ledge that you need to jump on. You have to run ALL the way up the stairs and drop to that ledge.
From there, have the healers on the MT and everyone else DPS the boss.
The exploit here is that he will NOT evade bug out on your group, his raptor will. Once you have killed the boss, zerg the raptor and win
You also don't need to worry about being watched, just DPS away and you will be fine.
Again:
Warrior runs in and doesn't kill the speaker until everyone is positioned (Bloodlord will not aggro as you run up if the speaker is alive). When everyone is positioned, kill the speaker, the raptor aggroes to the healers while the tank taunts mandokiir. The raptor can't reach the healers/casters/melee since they are on the second tier up on the "Bloodlord's Shrine Tower." Raptor bugs. Bloodlord is on the main tank who is just right of the stairs going up to the tower. Focus fire the raptor with casters mainly, takes a bit longer without rogues or melee, but melee can shoot. Burn Bloodlord down, then everyone jumps and you kill the Raptor.
