skullclan hunter

can we get the spellcasting progression to be 1 every odd level for pally cleric or favored soul instead of just paladin?

i think this would give the class a bit more flexability IMO

in the description you even wrote cleric/rouges make good skullclan hunters wich isnt all that accurate IMO with no CL given to other divine casters than paladin.

No

Actually I wondered that at some point, until I checked it. In PnP, Skullclan Hunters have no spellcasting progression at all, not even Paladin's.
You get to sneak attack undead and you get immunities from things that target Fortitude and Will saves, what more do you want? Paladin spell progression is just icing on the cake.

Clerics make the best Skullclan Hunters, because they give Turn Undead, two Domains, plus other bonuses, with just a level and no requirements, unlike the Paladin.
Also I would recommend taking Sacred Vengeance. 2d6 more damage against undead for utter destruction.

If you want divine progression, just continue with Shadowbane Stalker afterwards.
