while it could be a hassle for 1st session, I think that everyone would switch fast;
str->fort
dex->ref
con->fort
int->will
wis->will
cha->will
I fight the poison with my fists...
no thanks
Rather lump con and cha together. Physical and Mental fortitude. Then Dex and Str for reflexes and power to withstand or bypass force.
And Wis and Int for escaping attacks on your mind.
Still a bit forced, bit better than str and con together.
I would even say, if you put str and con in the same saving throw, you could as well ditch con altogether, as con's signature feature is endurance of your body even if you might be physically weak.
