Tank: Two skeletons arrive with him, a sword-and-shield and a melee. Stack them on the boss, facing away. Block their heavy attacks if they target you.
Dps: Clear the two skeletons with area damage while focusing the boss. Do not use a heavy attack on the shield skeleton while it blocks, or you go Off Balance.
Tank: A two-to-four-hit ice barrage on the aggro holder. It is blockable and does not hit hard, but it is the lead-in to Winter's Reach or Health Leech.
All: Interrupt this cast. If it lands, it fires an ice tornado toward the target that very nearly kills a DPS and immobilises anyone hit, which is why the boss stays facing away from the group.
Healer: He tethers a drain beam to a random player and heals from it for three to four seconds with large ticks; it can empty a health bar. Focus the target hard.
Dps: It cannot be interrupted. If it is on you, shield or self-heal and block through it.
Dps: He spawns a shadow copy that hits as hard as he does but has almost no health. Kill it immediately.
All: If anyone strays more than about ten metres, he charges a random player and begins chewing them for heavy damage. Interrupt it. Stay stacked near the boss and it does not happen.
All: A full-circle tail whip with a heavy hit and a knockdown. Step just outside the circle or block it; blocking makes it minor.
Tank: Enter first and hold as much of the room on Angata as you can, especially the ranged mages, facing away from the group.
Dps: Use area damage on the pack at the boss; focus the ranged enemies when needed and interrupt their casts.
All: About every ten seconds she summons a Clannfear, which leaps, tail-swipes and has heavy light attacks. Interrupt the summon if you can, and kill it next to the boss. Do not run from it.
All: She drops a small fire circle toward the aggro holder. Step a short distance out of it as it lands. The cast can also be interrupted.
Tank: Four Scamps around the room. Pull them in tight on the boss after taunting. Keep him still in the centre.
Dps: Kill the four Scamps first, interrupt their casts, and avoid their ground fire; the fight is then straightforward.
Dps: About every ten seconds he summons three skeletons. Kill them quickly with area damage, or they explode. The next wave is timed off their death.
All: A clear circle at his feet plus a strike toward his target. Step out of it; the tank simply blocks. Do not run.
Tank: A frontal cone on the aggro holder. Block it, and keep DPS and healer out of his front so it only ever hits you.
Hard Mode: Invoke the Scroll of Glorious Battle before the fight (achievement: Soul Splitter).
Dps: Healing orbs spawn where he started and drift toward him wherever he is. Kill every one before it reaches him, or he heals a large amount. On Hard Mode he starts at 5 million health, so nothing can be allowed through.
All: He raises his sword and places four fire pools on the ground one after another. Step out a little at a time, or dodge clear. Do not run off.
All: His heavy attack, marked by a white and yellow body flash, hits extremely hard. Block it. An unblocked DPS dies; a tank takes very high damage. If it is coming at you, block regardless of role.
All: After Ghost Fire or Heavy Blow he throws a fast fireball at a random player, which is almost certainly fatal. Whenever he raises his sword for Ghost Fire or winds up Heavy Blow, hold block until you see the bolt cast, then react.
All: Hard Mode adds no new mechanics: he starts at 5 million health and everything hits harder. Feast control must be perfect, and no one can afford to take a Heavy Blow or Magic Bolt.
