Hits for ~6000; flurries; sees invisibility; sees Shroud of Stealth. He is undead, as are the "a lost soul" adds.
Emperor Draygun, the Lich King, stands in the middle of the south wall in the south-most hall in the zone. Next to him is an untargetable floating book "Shadow Spine".
Once you engage Draygun, Shadow Spine will spawn five undead "a lost soul" in waves two and a half minutes apart. In each wave, the five will spawn at intervals of a couple of seconds, helping with targeting.
The "a lost soul" are not fast movers but do warp badly. They hit for up to 1750. It is essential that they are killed fast or they will despawn and make Draygun stronger (increasing his hitpoints and making him hit harder).
Emperor Draygun absorbs the power of the shadow into himself, growing in strength.
When undead Draygun reaches 85% health, a live version of Emperor Draygun spawns.
Emperor Draygun says 'Adventurers, normally I would slay you for even entering my fair city, but I see your efforts against this evil. Please, I must have your help to heal this corruption and restore health to my people.'
At this point, any damage done to undead Draygun will heal him.
Emperor Draygun's lifeforce returns for a moment, as he feels enormous pain.
Emperor Draygun absorbs the magical energies of the spell.
It takes very little damage done to undead Draygun to return him to full health.
Live Draygun will vanish and you can get back to attacking undead Draygun. The same process will repeat at 60% and at 35% health. (Note that the live Draygun will only spawn once at each of those points. For instance, Undead Draygun can heal from 85% to (say) 100% health but you won't see live Draygun again until 60% health.
