I know that there are several threads on the Lyris Doppelganger/Halls of Torment issue, one of which I started myself, but I'm really getting fed up with this and finding it impossible.
It's a level 30 quest; I got completely creamed as a level 30 nightblade, so came back at level 37 for another pop. I managed to stay alive for a good 5 to 8 minutes throwing everything I had at it, virtually constantly, but I don't think I managed to drop its health below about 75% with it rapidly topping up to 100% many time due to it's feeding on Lyris.
The usual melee and skills not working/dealing damage issues didn't help, nor did the fact that my ultimate skills wouldn't charge in the Halls of Torment and and dropped after each death (after 3 deaths I had no ultimate charge and no way of charging).
I've tried toe-to-toe fighting and ranged combat, but as a moderate health/moderate armour/moderate DPS night blade this feels like a no win situation; I just can't deal enough damage quickly enough to even come close to countering the healing from feeding. The only way I can see to win here is being able to deal massive amounts of damage quickly, which is well beyond the scope of my "play the way you want to" night blade.
I'm not a bad player, but I don't see my character winning this combat into he's gone veteran (especially without access to ultimate abilities) meaning that I can't progress in the main story arc.
I don't want tips, as I'd like to work it out for myself, but I still can't see a way, with the skills I have, of being able to simply deal enough damage.
I just felt like registering another moan!
