Is Auto-Battle possible?

As it turns out, all attacks are targeted properly for Charm + Confuse. Attacks can't hit your party, and healing spells can't hit the enemy. However, unless you changed it so that Muddle cannot be dispelled by attacks, it wouldn't be very useful (one hit and your character is just on Charm status, attacking your party). This would probably mean that you'd have to replace Muddle entirely, as it would be too broken to use normally. The other disadvantage is that I doubt you could apply Charm through a relic, so an auto-battle relic wouldn't work this way like it would with Berserk. And you might not be able to increase damage like with Berserk to make it potentially useful (and not just save you the effort of putting in commands).

The main advantage of Charm + Confuse is that your characters are able to use special attacks like Lore or Steal as well as magic/fight. It would give more variety.
