Howdy all,
This is a variant I've been thinking about for a good long while, and I thought getting community advice would be a good idea. I imagine this can be easily manipulated for minmaxing, but I haven't put my mind into thinking of how yet.
I want to run a campaign where classes get to choose what stat their abilities are based on. A world where there could be such thing as a Strength Wizard, a Charisma Fighter, a Dexterity Bard, and everything else in between greatly appeals to me.
My immediate thoughts are that it mostly affects spellcasters. Fighters really just use Strength because it benefits them most, while spellcasters actually use their class-stat more specifically.
What rules should I change to bring this about? Should I allow a Charisma Fighter to use his Charisma in lieu of any Strength requirements for Feats? How far down the rabbit hole should I take this concept, and what advice do you have on it? Thanks a bunch!
The Con-Witch (original scarred witchdoctor) has been done. It offered supreme single attribute dependence for a spellcaster but still wasn't considered horribly broken by most at the time it was retconned. I won't say nerfed, the new version is arguably stronger. With the right infusions you could make a kineticist who only cares about their con stat right now.
There isn't a lot of stuff in the fighter class that'd matter (even the feat qualification isn't any big deal), nor in most non-spellcasters, but 4 and 6 level spellcasters tend to have class features as well as spells which depend on some ability score (e.g. Smite). 9-level spellcasters, well, I'd expect to see a wizard who always acts first and who puts his foot behind his ear for extra power. The yoga wizard, based on Dex.
