Ohhh congrats xD
And don't worry. I still have a lot of edits to make before catching up lol. Should get to it soon now that Spirit Arrow's demo is out tho!
And well... I really wanted to do that, but I don't think it's possible without some plugins. The best I did was give Lianna and Jeanne a debuff when fighting wargs that make them more likely to be targeted, but I don't think I can use the player's stats in the enemy AI. I can only make enemies do stuff like use Mana Drain when their own MP is below a certain threshold and such. The only way of doing what you said would be scripting an event in the middle of combat like a cutscene that would check each character's MP and then decide if the enemy will make an extra turn using Mana Drain on one of them... Which I don't really like either.
