Albino's Nightingale Archer is pure thief except for its use of Illusion. The name sort of gives away that it's focused on Nocturnal: http://tamrielvault.com/group/character-building/forum/topics/character-build-the-nightingale-archer

Anyone know of a fun duelist build that uses daggers? No swords. I didn't really like any of the ones in the hall of fame.

A Dagger Duelist, you say? 

Does anyone know of a assasin that uses poison to deal most of its damage and that does dark brotherhood and thieves guild quest line

And that is a vampire

Try out the Berne Clan build. It is a vampire assassin that deals massive amounts of poison damage. Easily 1000+ in one attack over the course of 10 seconds.

Im dying. I need a new build. Throw your favorite build from the vault at me. 

pls save me...

Transient Sorcerer, The Sorceress, The Berne Clan, The Kingslayer, The Vancian Wizard, The Trebbite Monk, The Dark Purveyor, The Creature of Lake Ilinalta, and just finished the Paralytic Mage (which I quite enjoyed). There are more, but I'm asleep on my feet right now. Perhaps tomorrow ;D

Any Paladin / Evil Paladin Sword and Shield builds? Don't mind what other skills it has
