I need some help. I started the soul cairn quest set and my life started draining when I opened up the soul cairn portal. Luckily my character is a caster and i can keep up with the drain and fight at the same time but my only problem is that it hasn't stopped even after completing the quests. I'm a werewolf on the Dawnguard side. I chose the soul stone route. Got MY soul stone back and completed that quest. Do I have to hand it in or something? Do I have to capture more soul stones? I'm completely lost.

Well you shouldn't be losing health if Serana took part of your soul.

Sounds like a bug to me. Check your active effects to see if anything sticks out to you

Nothing but the massive amount of stat gains from being a werewolf, having archmage robes, a dragon priest mask and being argonian. I posted a video in one of the bug list threads. But here it is for you to find it faster. http://www.youtube.com/watch?v=VJu8ykn8Vag The only stat debuff I had was from my soul being in the stone. Which when I recovered it the debuff disappeared but I was still losing health. Thankfully i'm able to out heal it and not lose mana. So I could continue playing but it's kind of annoying having to heal myself as i'm playing.

Odd. Try eating a soul husk?

Soul husk potions last for sixty seconds. Serena's mom gave me some, but I don't think you can get very many from her.

It happened to me last night. Though I noticed it wasn't draining my health like standing next to the giant gems so I ignored it, it stoped after one of the teleport jumps you do there. I did notice the sound it made followed me into the real world. Haven't played today so don't know if the sound will still be there when loaded up.

Also there are soul husks all over the the place there. Harvest them and eat them (they're in food not ingredients). Stops the health drain by giant gems for a bit, doesn't do squat with the glitch effect.
