Going through the spell list, there’s an awful lot of spells that are incredibly funny in the context of bedroom pastimes, here, let’s assume it’s heroism and Bear’s Endurance.
Technically, if you look at what Charisma rolls do in practice, it’s more akin to Constitution but for your mind. I personally like to use Constitution as the physical prettiness score and Charisma as the “force of will” stat.
I know that’s counterintuitive as hell, but it’s what the rules lead me to believe. You don’t roll Int/Wis to resist having your soul rent asunder, after all. Besides, I think this lines up with how attractiveness works irl. I’ve met plenty of physically attractive people who become absolutely repulsive when you just get to know them the tiniest bit.
That’s weird. Wisdom has always been the resistance roll for soul stuff in my memory, except for its weird foray into the physical with perception checks.
Maybe it’s a 5e thing. I only got into DnD in 4e when I was a kid, so maybe that was the transition point for that. As long as I have been playing, wisdom was for avoiding/deflecting psychic effects whereas Charisma was for withstanding effects that can just hit you with no chance of escape. It’s analogous to making dex save to dodge a poison dart trap, but having to make a Con save to resist the poison itself.
The way I have been exposed to it, you use Intelligence to see through an illusion, Wisdom to avoid being charmed, and Charisma to avoid being NPCified into a mindless thrall of the big bad.
I suppose it’s better to say that for as long as I have been playing, the stats for “save or die” saving throws were either Constitution or Charisma. In fairness, these rolls were rare, but I have been trained that when the DM says “Make a Charisma saving throw” my bowels automatically loosen while I dig out my next character sheet from my folder.
