So I'm on mobile playing FFT: WotL version. I'm in chapter 3 and I set up a team to do the auto-JP farm, meaning I wanted set everyone to AI while they all hit for 1 hp at a time and let the JP roll in without have to sit there and command each attack.

So I did the standard thing I read others said to do:

• Killed all but one enemy left on the field
• Used Rend Power on everyone to get within 1-3 PA.
• Used Rend Speed on the enemy so they have very few turns against my party
• Used an Arithmetician to frog the entire field.
• Set each of my players to AI-mode specifically as "Berserker" and selected the enemy frog as their target (won't even let you target teammates - I tried)

What I discovered is that my team will refuse to attack the last enemy left. They will simply surround it then pass each turn without attacking. The enemy frog will attack my party every turn it gets. I had to turn AI mode off everyone and manually hit 300 HP down 1 at a time.

Does anyone know where I went wrong and what I'm missing? I just can't understand why there's an AI "kill something mode" but they just pass their turns.
