Paladin undead spell DD replacement

Replace the undead DD spells that Paladin’s get with class specific undead spells.
It reflects the Paladin’s dominance over undead and the undead’s distain for Paladin meddling.

I feel the Damage is balanced with other spells from other classes as well as the current DD spells. It is a fast cast long recast DD with a DoT and a significant hate component.
