is there anything that affects vampire lords strength? yesterday on my non Mage level 78 I could 3 hit a bandit marauder now on my level 79 Mage It takes like 10 vampire drains. also my non Mage was a non Mage who got powers from sera after dawnguard, and my Mage is early on it Harkons quests.

Do you have Serana as a follower?

Yea for some reason when using Serana as a follower your drain attack becomes weaker

I did actually.

It seems that the 360 is still beta testing the game I am kinda glad the pc and ps3 are getting it a month later and its still quite shocking that this did not get fixed in beta. Since this seems like a major bug.

Depends how much of a bugger it is to fix. They may well have 'fixed' it and that fix knocked something else out even worse...

Dismiss her and you should be good to go.

Have you noticed how weak the vampire lord is. Got all the necessary items/perks and still weak. Not to mention the mages and vampires you come across annihilate you with fire.
