7) I agree with @hyenagrin that Mending would be an absurdly useful cantrip.
8) since this is a less chunky couple of questions. I tend to wind up taking high CHA or DEX given a fondness for fast-moving “face” characters. Occasionally if I’m playing a cleric my DEX will be pretty low. And if I’m not playing a cleric WIS is often dead average if not lower.
