So why do enchanter wizards need high charisma?

[MaxWilson]

So tell me why WOTC in the PHB thinks a high CH is important enough to be your second highest stat after IN and before DE and CO.

Never played an enchanter so I am confused. Are not the spells driven by you IN stat?

Well, they don't really. The PHB guidance is bad advice. It wouldn't be a terrible idea to invest in Persuasion or even Prodigy (Persuasion) if you're planning on playing a trickster, but investing in Charisma pays very little return for the cost.

I wish someone had given me the advice to invest in AC (heavy armor and shield proficiency) instead of Cha, when I first played an Enchanter. I would have gotten way more mileage out of my Enchanter features.
