So i've been tossing around the idea of making an undead hunter for years. Now that vampires are a thing....why not? I've got a few ideas, but nothing solid.

Paladin/Bard- STR as a primary stat, CHA as a secondary. Mostly paladin levels for UMD, bless weapon, death ward, etc. Decent number of bard levels for up to level 3 or level 4 bard spells.

Cleric/Paladin- Weird stat split with str/wis/cha. Focused mainly on buffing up and meleeing rather than spellcasting.

Ranger/Paladin/Rogue: Bane of Enemies and Bless Weapon with a few UMD tricks.

Paladin/Bard/AA: The only ranged concept I can think of.

Cleric/Paladin/Bard- Spellcasting with WIS/CHA.
Theres a reoccuring theme here. Basially
-STR based. DEX based against things that are crit and sneak immune=bad idea.
-Paladin. For rp reasons, and for easy access bless weapon. Decent undead turning is a plus, but not needed.
So. Thoughts?
Sidenote: are there any non-LG dieties that support paladins and undead hunting? Going with a generic Lathandar/Triad undead hunter seems too easy.
Sidenote: Does divine damage on bless weapon stack with the divine damage from a lesser moonblade?
