We don't talk about Pun-Pun
Ugh, no, let's not go back to the Combat Expertise days. Sure, it gave you a reason to want Int, but beyond 13 it was just more skill points. As for helping with Int-based skills, sure, unless you have a Wizard or something in the party, then it's not all that effective, since you know they're going to have an Int of 20 before long.But some people are talking about swapping any ability they want in for strength. That's why it's difficult to have these discussions. On the other hand, intelligence can be useful to a fighter based on skill proficiencies.
If you want it to be useful in combat I could see it adding some bonus, but then you get balance and complexity issues. Not a bad idea I'm just not sure what it would look like. Seems like you'd need a whole set of strength (or dex?) + int or wis or cha modifications. How far does it need to go and which classes would get the benefits? Go back to having feats that require a minimum X [ability score] that primarily benefits martial characters?![]()
However, I did have an idea for what Intelligence could do; Each +1 ability modifier for Intelligence grants a bonus Reaction each turn that cannot be used to cast spells.
