So i'm near the beginning of the dawnguard quest and getting the Moth priest. I have him out of the prison and used vampire seduction on him as it told me to do.

Now its telling me to feed on him to make him my thrall.

I cannot figure this out for the life of me. How do I feed on him?

Walk up and press 'A' on him, then choose feed.

If that does not work, I sense you might have found a very irritating bug, and shall provide you this loudspeaker to assist in the ensuing FUUUUUUUUUUUUUUUUUUU

just go as if your going to talk to him then a little menu will pop up that says feed or talk. If that dose not work i can't help you brother.

Yea not working. Do I need to be in vampire form?

Nope, normal form. I'm thinking you might be wanting this *offers loudspeaker*

Well that's just wonderful then. This character with over 150 hours now can't do this expansion quest.

Well that's 20 bucks down the drain I suppose.

thanks for the help.

No older save you could revert to? Damn.

I have 3 saves around this point and none of them work. Nothing earlier than that.

Just outta luck I suppose.

Guess its time for some COD

There's a game I miss. If my interwebz wasn't so sketchy (thanks BT) I'd bring you into the squad for some greeny stompage. Well, as long as your EU based, I'm sure transatlantic laggage wouldn't improve things.

Vampire Seduction only lasts a certain period of time. If you don't feed on the person in that timespan, you have to wait 24 hours for your Vampire Seduction ability to come off cooldown.
