Any deity/domain restrictions?

Deathbound and Undeath (both are in SpC) are the domains of choice for a necrolyte cleric. But wizards still get nice necromancy toys that you don't; that's where the Divine Magician ACF from Complete Mage comes into play. Start as a Cloistered Cleric, then trade your Knowledge Domain in for a free Wizard spell of each level that you get to cast with Wis.
