I have killed over 250 restless dracoliches and servant of the sleeper combined. Spend hours keeping all 6 ph down. Can someone offer me some hope that this mob still spawns?
My group was running towards Kael for the mission tonight when I noticed he was up, just wandering around so we killed him.
I hunted it tonight and killed it. Took about 2 clears of dracoliches in the area I did spend an hour or two on other nights and never saw it. It's a bit of a pain since they all roam so the ph's are not obvious. I just ran around slaughtering.
