Attacks and Abilities
This is a fairly simple fight where the boss has 2 interesting abilities.
Firstly, he will spawn Frozen Orbs (1 in 10 man, 3 in 25) which pass through the raid, ticking AoE frost damage within a fairly wide radius. These need to be killed quickly as he will cast Whiteout soon afterwards, which does large raidwide damage. Whiteout stacks a debuff which will increases frost damage taken, so each cast imparts more damage on the raid. If the orbs are not taken down, healers will not have had a chance to top up the raid and people with damage will start dying to Whiteouts.
Melee hits from Toravon will start stacking a Frostbite debuff which adds a significant DoT to the damage taken. A 2 tank setup will need to taunt Toravon as the debuff on the other tank reaches 4 stacks, which allows time for their own to clear. At the start, tanks can handle a higher number of stacks, but as the raid gets more stacks of the Whiteout debuff it makes harder for healers to keep tanks alive. In addition, he sometimes immobilizes the tanks using Freezing Ground. This will prevent the tanks from dodging Frozen Orb.
The original advice on this raid has been to spread out to avoid multiple raid members taking hits from the frozen orbs, but this may make it harder for AoE healers to keep people up. With reasonable raid healers, the best tactic appears to be to take down the frozen orbs as soon as possible (even using melee dps if the raid is short on ranged) to allow the healers time to top up the raid before the Whiteout. If people take damage for longer by avoiding instead of DPSing the orbs, the chances of deaths on the next Whiteout increase significantly.
Healing will get more difficult as the raid gets more stacks of the whiteout debuff, but a 2 tank, 2 AoE healer, 6 dps setup in 10 man or 2 tank, 5 healer (one tank healer), 18 dps setup in 25 man has been seen to succeed.
