So +2 CHA outperforms every other feat except eleven accuracy? This is my first character/game of D&D, sorry for lack of knowledge here.
There's only a handful of feats I would recommend for a cha pure caster. Alert, Inspiring Leader, Lucky, Actor.
I'm not sure if +2 charisma is better than all of those but it's really good. Any of those options are good. Pick the one that interests you most.
