Strat -
Burn named.
Will spawn adds at 75%, which must be Offtanked for a while.
When killed, they will buff the named.
Will randomly port 3 people to the pools + lower platform throughout the fight, and spawn little heroic adds that can just be killed by raid.
Burn named down to 15%(ish), burn adds, kill Named.

Fight the name on the same platform he is on. He spawns three adds. Bloodmaster, effigy of youth and effigy of beauty sometime into the fight. (75%?).
Bloodmaster has to be killed asap. During the fight a raider will be ported in one of blood pools or down the ramp spawning a blood sacrificer. Up to three raiders at a time. Bring them to raid. Kill them asap. If they stay too long it's a fail condition. Keep fighting the name. When he is down to 15 or 10% switch to effigies. If you kill them too early Buran gets buffed. I think a damage increase and something else. Sorry. Can't remember.

Finish the name.
