can someone tell me how to remove level\energy drain that vampires give you without a restoration scroll?

Restoration spell, or lesser restoration, or visit a preist, or kill the character and bring him back to life

The level four cleric spell Lesser Restoration is the easist. If you don't have a cleric in your party, and you don't mind cheating, you can give yourself a scroll by doing the CLUAConsole:CreateItem("RESTORE") thing. If you don't know what I mean see the cheats section.

A couple things to keep in mind...

Your character will often end up fatigued after restoration, for what that's worth. Also, not ALL temples will offer this service. I generally hit the one in the Promenade, it costs about 750gc if you've a decent reputation.

And even less if you're a tea leaf with a high pickpocket skill
