Unless you plan to spend most of your time playing from level 1 to level 5, what's the point of increasing your WIS score at the expense of your CHA score? Aura of Protection sums CHA to all your (and your companions') saves.I, uh, what? What use does Paladin have for wisdom?
The Wisdom saving throw is one of the three important saves (DEX WIS CON). The CHA save is shit.
But it is a bit hyperbolic, since Paladins get more prepared spell slots from CHA. That is worth a bit, although not terribly much, since Smite is always there as their strongest spell slot outlet.
Yeah I kinda forgot that Aura of Protection scales of CHA and is pretty damn good. I thought it went off proficiency bonus. As soon as you take 6 or more Paladin levels a high CHA modificator becomes really good for them, because that ability is bonkers.
Still 1-5 a high WIS modificator arguably brings more to the table than CHA for combat. But CHA is usually the strongest noncombat ability score, so everyone has it high in paper.
