For those who have not yet done it and have hit 80 already, there is a daily quest you can take in Coldarra which puts you in control of a red dragon with skills identical to those found on the dragons you control in phase 3 of the Malygos fight. I got myself killed about 4 times trying to kill but a single dragon (you kill 5 for the quest) with my own, so I 'd advise anyone who plans on raiding to DO THIS QUEST! Over and over again, if necessary.

The quest is called Aces High! and it's a followup from a pre-requisite started at the quest hub bubble for Coldarra.

The quest asks you to fly up near the top of the Nexus (Coords: 29.5,24.8) and accept a quest from Corastrasza. Talk to her after accepting and you're put on a drake, and ordered to fly up above you and kill 5 Scalesworn Elite.

This is no easy task. The elites will rip your drake apart if you're unprepared for them. Fortunately you get a parachute if you lose your drake, but it's not very useful when you're forced to wait for a very slow fall all the way back down to the ground.

The drake has 5 main spells: 

Flame Spike: ~1k Damage, puts a combo point on your target

Engulf in Flames: A DoT dealing 1500 Damage every 3 seconds. Amount of combo points on your target extends the duration of the DoT. 1-6sec, 2-10, 3-14, 4-18, 5-22

Revivify: Heals your target for 500HP per second and lasts 10 seconds, awards 1 combo point, and stacks up to 5 times.

Life Burst: 60-yard AOE Heal, increases caster's healing by 50% and duration/healing done scales based on combo points. 1pt:5000/5sec, 2:7500/10sec, 3:10000/15sec, 4:12500/20sec, 5:15000/25sec

Flame Shield: Shields the caster, reducing damage taken by 80%. Time scales on combo points: 1:2sec, 2:3, 3:4, 4:5, 5:6

The drake also has your generic ultra-speed-boost spell, as they all seem to have in one form or another.

The spell rotation to kill the enemy dragons is rather simple:

1: Stack 5 Revivify on yourself

2: Stack 5 combo points on your target, Engulf in Flames

3: Refresh your Revivify to keep the duration going

4: Stack combo points again, Engulf in Flames

Rinse; Repeat

The shield and AOE heal are designed more for the group scenario (cough, Malygos) and fairly unnecessary for this quest, but it's a good idea to get yourself very well-acquainted with them anyway.

Happy hunting everyone, and good luck! Keep in mind that this quest is a daily, so if you think you could use the practice, by all means, use this as practice.

I know I'm not the only one who wants to witness the skullfucking of poor Mister Malygos.
