Fight map
Hover a number on the map or in the text to highlight the spot and the strategy line. Marks follow the fight scripts.
A 10-player fight in the locked library. No tank needed: Aran stands still and hits random players. Main danger: Arcane Explosion and Flame Wreath if someone leaves the ring.
Regular spells
Every 2 sec a cast on a random player: Frostbolt for 3,500–4,500, Fireball for 3,910–5,290, Arcane Missiles for 1,260–1,540 per second over 5 sec. All three can be interrupted, the missiles first. Every 5–20 sec either Counterspell interrupts the casts of everyone within 9 yd of Aran and locks the school for 10 sec, or Chains of Ice holds a random player for 10 sec.
Every 30 sec: a big spell
The first one at 5–10 sec. Aran jumps to the center and picks one of three, never the same one twice in a row. They cannot be interrupted.
Flame Wreath
5-sec cast. Three random players get a 3 yd ring for 20 sec. Stand still; casting is fine. If you leave a ring, yours or someone else's, 1 sec later Explosion hits all allies within 45 yd for 3,238–3,762. Step back in within that second: no explosion.
Blizzard
Summon Blizzard: 2-sec cast. For 25 sec the blizzard moves clockwise 16 yd from the center. It leaves Blizzard circles behind: 13 yd, 10 sec, 1,313–1,687 every 2 sec, a 65% slow. Move ahead along the circle or to the very center.
Arcane Explosion
Massive Magnetic Pull pulls everyone to Aran. 1 sec later Mass Slow: −60% movement speed for 10 sec, dispellable as magic. Arcane Explosion has a 10-sec cast: 9,000–11,000 and a knockback to everyone within 21 yd. With the slow you can run about 25 yd: run at once.
Mana below 20%
Mass Polymorph: 2-sec cast, the raid turns into sheep for 10 sec and heals 7% per second. Blizzard stops. Aran conjures water for 2 sec and sits down: Drink. 15 sec after the polymorph starts, Pyroblast: 6,800 Fire damage to everyone within 100 yd. A direct hit from a player gets Aran up earlier: Pyroblast comes 1 sec later, and if he was still drinking, he manages to drink a Mana Potion.
40% and the timer
At 40% Summon Water Elementals: four Conjured Elementals with 13,972 HP each for 90 sec, Water Bolt for 189–231. Frost spells do not work on them. At 12 min a Shadow of Aran rises at 8 points along the walls and hits the whole room with volleys.
Healers
By Pyroblast everyone must have more than 6,800 HP: after the polymorph there are 3 sec left to heal. Dispel Chains of Ice and Mass Slow.
DPS
Casters stand more than 9 yd from Aran. Assign interrupts in advance.
Common mistakes
- A player left a ring: Explosion hits the whole raid.
- Running from Arcane Explosion started too late: the margin is only 1–2 sec.
- Aran was hit while drinking before the raid was healed: Pyroblast comes 1 sec later.
