Partial resists work. I've had people complain to me a lot about it; usually about binary spells though. I don't think I've ever had someone complain about partials on damage spells or anything. Usually it's: I can resist almost all partial damage but fear still lands on me!
It would probably be better to add a spell penetration stat to npc types than tack it onto cha. That would require re-balancing a lot of npcs in people's databases for a select few encounters, since it's likely npcs will have normal cha for that level even though it barely does anything for npcs. Even baseline default of -75 resist with 75 cha would be a pretty big hindrance to a lot of players. You're talking a baseline 30% chance to be hit with spells with default cha.
