Oh yes. CHARISMA. One of the cursed stats, because I usually use only my character in dialogs, and this stat is crucial then. And it is always required, whether or not you are a deceptive rogue or intimidating warrior. I wish they had more intelligence checks, just to crush your opponent with "facts and logic". Detect thoughts works kind of, but this is not the same.
And it would be probably nice to also have some way to proceed with Minthara without killing everyone in Druid grove, because as I remember - the Grove itself is not their main goal. This way people like us would be able to replay the game more
