Viscidus

Melees for around 1000 on a NR-geared tank. Hits very fast at first, but progressively slows down.
Takes 50% reduced damage from all attacks.

Poison Shock: AoE Nature attack for ~1200 Nature damage every 10 seconds or so. Poison Shock has a radius of 15 yards, so be very careful to stay away when not trying to shatter him once frozen.
Poison Volley: AoE spell cast every 10 seconds that hits for ~1500 resistible Nature damage on hit and will apply a dispellable DoT that does ~500 Nature damage every 2 second for 10 seconds. Similar to Lord Kri and Princess Huhuran. This volley ignores LoS and has a range of 100 yards, therefore it is very difficult to avoid it. Nature Resist gear can greatly mitigate the direct damage, but the DoT is unresistable and therefore highly lethal. Poison curing must be set up for the raid so that no one is hit by more than one tick of the DoT.
Toxin Clouds: These are spewed out every 30–40 seconds. The cloud hits anyone inside it with ~1500 unresistable damage every 2 seconds and slows movement speed by 40%. Similar to Lord Kri's death cloud. A single bolt will predate the Toxin Cloud (it is the only time Viscidus spits on a single target), so move away asap from the landing point of that single bolt. The clouds look fairly small, but their damage radius is larger than their graphic so beware!

The Three Frost Stages

Viscidus must be slowed by Frost attacks in order to defeat him. Frostbolt, Frost Shock, Icy Touch, Frost Strike, and Howling Blast count towards this objective. The strength of the Frost attack doesn't matter, only the number of hits, so use the fastest Frost abilities possible. Frost attacks are required, but other attacks too, freezing is faster if more people are attacking it.
"Viscidus begins to slow." - Movement and attack speed reduced by 15%. This phase begins after 100 frost abilities were used against the boss.
"Viscidus is freezing up." - Movement and attack speed reduced by 30%. This phase begins after 150 frost abilities were used against the boss.
"Viscidus is frozen solid." - Movement and attacks cease completely. At this point the raid must switch to melee attacks to shatter him. This phase begins after 200 frost abilities were used against the boss.

The Three Melee Stages

Once Viscidus is frozen he must be shattered. This needs to happen very quickly or he will thaw out and continue attacking the raid. Melee attacks are required. Everyone, including melee and ranged characters, should run up and hit him. Viscidus only explodes when enough hits have been dealt (after about 75).
"Viscidus begins to crack." - Continue melee attacks.
"Viscidus looks ready to shatter." - Continue melee attacks.
"Viscidus explodes." - Viscidus shatters into multiple small "Globs of Viscidus" in a circle around the room. These Globs will begin to move towards the center of the room, slow at first, but continuously and steadily gathering speed. Once they reach the center, Viscidus will be reformed.

Globs of Viscidus

Every time Viscidus is shattered, he splits into 1-20 Globs of Viscidus - each one representing 5% of his total HP. If he is below 5% when shattered, he will die. Each glob takes 10-15k damage to kill.
Globs must be assist trained to death, as DPSing one has no effect unless it is killed. Globs cannot be slowed or stunned so you must DPS fast and hard.

Transition Aggro

Viscidus has a nasty tendency to aggro someone right as he reforms and run off after them. Since he is not chilled at all at this point, and he is untauntable, it is very difficult for the MT to catch up and get him back. Unless he is picked up and tanked very quickly, he will likely run around killing healers until the raid wipes. There are various theories as to what makes this happen, but it sometimes seems as mysterious as Onyxia's Deep Breath.
Some people say that DPSing blobs without killing them (especially with AoEs and Multishot) causes transition aggro. This seems rather unlikely, as healers get transition aggro as often as DPSers.
Some people say that players standing too far away from Viscidus will pull aggro. In any case, it is not a good idea to run out of the room too early after a transition; if he aggroes someone out of the room he will instantly reset to 100%.
Some people say that Viscidus has a limited-radius aggro wipe, or an aggro wipe on a limited number of the closest players, and that the players standing further away from him should not do any healing or curing for 5 seconds during each transition.
