User blog:Steven Bomb 17/A few questions

I'm playing Fire Emblem Shadows of Valentia Echoes and I have a few questions

1. When you retreat from a fight do the enemies ever reset? I'm having a little trouble with Duma Gate, Valbar and Kamui are pretty far from their next class changes because everytime I try to get them into a fight the battle ends. I took out the witches then retreated so I'm thinking of just defeating a small handful of enemies, retreat, rinse and repeat. I'm on casual so there's no risk.

2. There's a rating next to my character's names, what's that for?

3. All of the wine and ale have gone dark, does food spoil or can only certain characters drink those items?
