Yukiko and Mudo

[🅶ila]

Short of overwriting it when her persona fills up, is there any way to stop/limit the AI's usage of Mudo? Would be happy to exclude just that one skill to only direct commands. Otherwise, her skill choice is pretty decent at attacking while maintaining party HP.

I'm in the second dungeon and she's just constantly spamming it, even when she can exploit an enemy's weakness with an AOE attack. 4 enemies weak to fire, and here she is casting consecutive failed Mudo's. 🤣

I think the more pertinent question is, "Why are you using the A.I. instead of controlling the party yourself?" After all, they added that to base P4 for this very reason...

There's a reason why the "Marin Karin" meme exists...

Despite the "Marin Karin" meme, the AI in P3 FES wasn't bad as long as you actually used the Tactics menu to swap tactics as needed.

Supposedly the AI in P4 is pretty bad regardless, so unless you're doing some sort of self-imposed challenge I suggest you switch to Direct Commands.

If you insist on using the AI, you can try to change her tactic from Act Freely to Full Assault and see if she starts using Agi spells. Be aware that she won't use Dia spells with this tactic though.

change to "focus on attack" for yukiko keep all mudo, agi, and maragi. Let's see how the com will act, iirc she will use agi to enemy that weak to fire more, unless if you only keep maragi and mudo then yes her tactics will ONLY prioritize mudo, she good at using AOE healing skill when i change her tactics to focus on healing though
for whatever reason the game doesn't want to use AOE attacking skill

i use "focus on attack" for kanji and sometimes he use primal sometimes he uses vile, i keep both skills depending on situation, (i use direct command, but sometimes when i get bored, i use tactics, during my test single target skill is more reliable if you wish to play on tactics)

There are better AI mods for all 3 games, if you prefer to auto-battle (even though it's not how the game was meant to be played).

I was just going to link the mod toughnails linked

The party AI was gutted beyond belief with the release of Persona 4, and this has only ever been made worse with each following release
spells like Mind/Power Charge, EVERY buff and debuff except for Dekaja and Dekunda, are completely unusable by the Party in every instance, making them wasted slots on your members' skill sets

the mod creator goes into better detail on some of the very questionable choices atlus made when 'developing' 4/4G's ai regarding rng checks
