Anyone who wants to play paladin generally wants to play a goodie two shoes that follows the rules, is lawfully good and guess what…. It’s boring. When your playing as a paladin, I want to role play as a heretic. A paladin that chose to be lawfully evil. Here would be how I would homebrew them in.
Races to RP As
I would want to play as a Drow or Human. I can see arguments made for half elves and gnomes as well.
Powers
Level 1: Minor command Dead: cast a wisdom with DC of 8. Undead fights everyone unless makes a DC save of 12.
Level 3: Hellish Rebuke: make a 1d10 burn to any enemy in LoS with a dc of 12 (dex), if save deal 1d4
Level 5: Crown of madness: charms an ally unless save of 16- lasts 4 rounds [free action]
Level 7: touch of madness: reduce chosen stat roles by 4, add 4 to chosen
Level 9: Bestow Curse: target rolls all chosen stats with disadvantage (can be removed by magics)
Level 12: Blight: deal 1d6 damage every round to enemy until concentration check fails [free action]
Let me know if you agree.
