In the old D&D rulesets Charisma was the stat which contained stats like intimidation, reasoning and charming. But as you are creating a new ruleset/system, you apparantly want to sophisticate that classic persuasion/communication system and that's a good decision I think. But imo it shouldn't be interwoven with the mostly combat skills. These stats are important for your dual-dialogue system, so why not making them more important in your ruleset?
It would stay a solid system with a higher focus on communication and interaction. Just think it over.
Yeah i would really like to see a separate charisma style primary stat as well.
The proposed system...
Persuasion
This is determined by equipment bonuses only. Persuasion gives you bonuses when trying to intimidate, charm or reason with your party members or NPCs.
... sounds to me like it would end up like a mini dress up game where you are constantly equipping different rings/amulets and stuff when you talk to an NPC.
Perhaps something like:
Charisma -> Charm / persuasion
Charisma (+ Strength bonus) -> Intimidate
Charisma (+ Intelligence bonus) -> Reasoning
Plus perks/talents to further augment.
Should "helps you figure out NPC stats and resistances" not be part of Perception rather than Intelligence?
