About 3 months before DG was released i made a class build to hunt the Undead and serve Meridia. Now after taking that character through Dawnguard i have revised him a bit and would like to share the build.

Race: Any
Skill Trees: Archery, Restoration, 1H/2H, Light Armor, Sneak, Enchanting
Stone: Atronach, Lord, Lady, Shadow
RP Equipment: Dawnbreaker, Dawnguard Armor, Dawnguard Weapons, Crossbow
Shouts: Drain Vitality, Elemental Fury, Slow Time
Spells: Vampire's Bane, Sun Fire, Stendarr's Aura

Revision: Originally i used Destruction for close range with my Dawnbreaker (Fire spells) to take down the undead, as well as Conjuration for Bound Bow at long range. Now both of those are useless since the Crossbow and Anti-Undead Restoration spells are available. This build is very akin to Witch Hunter style builds BUT Undead are immune to poison so Alchemy is out. I can say that this build was fun and effective against the Vamps in DG and i hope it provides some insight for those who view it

Sounds sweet! Might have to do this after Dawnguard is released for Ps3
