Want to get this started for 2 reasons. 1) People mentioned there was no discussion about this fight and 2) It's after twins tonight.
Here is a general outline thus far for heroic,
1)
Frost Spheres.
There are only 6(?) orbs (Named: Frost Sphere) in the air, ever, that can be dropped down to do Permafrost. (Heroic mode only, normal mode is infinite orbs.)
Permafrost
2)
Adds.
Nerubian Burrowers: (Come while Anub'arak is
above ground)
Able to be stunned, snared and interrupted.
Cast a Shadow Strike that 1 shots people if it goes off. (Long cast time, can be interrupt)
Shadow Strike
Cast expose armor on the tank that stacks (This is why tanking more then 2 is a pain).
Expose Weakness
Cast a stacking frenzy when close to other Nerubians that increases attack speed (Like Auriaya adds but with haste instead of damage).
Spider Frenzy
Cast burrow that puts them underground for a set amount of time causing them to add themselves to the next spawn of adds. This is canceled by placing them on permafrost so they are unable to burrow.
Swarm Scarabs: (Come while Anub'arak is
below ground).
They come out with a 20k threat lead on random people and are immune to taunt.
They have a stacking DoT (1800 every 3 seconds?) on anything they hit that lasts for 1 minute.
Acid-Drenched Mandibles
They go enraged after a certain amount of time.
Determination
3)
Anub'arak.
(
Above ground)
Casts an ice shear on the tank stunning them.
Freezing Slash
Casts penetrating cold to random raid members dealing 6k frost damage every 3 seconds for 18 seconds. This is a constant through out the entire fight.
Penetrating Cold
(
Below ground)
Casts pursuing spikes. This will 1 shot a person without an immunity like BoP. It starts slow then speeds up to absurd speeds. The only way to stop it is to run it over a permafrost (this consumes the permafrost).
Pursued by Anub'arak /
Impale
In heroic mode it is important to drag it out as long as possible as there are only ever going to be 6(?) permafrost's for the entire fight. Druid res/BoP/Potions of Swiftness etc.
(At 30% health)
Casts Leeching Swarm. Releases a swarm of insects that attack the caster's enemies, leeching 30% of each target's current health every 1 sec. A minimum of 250 health will be leeched. This heals him. Can be AMS'ed or taken away with immunities to spells. He applies this at a frequent rate.
