That is funny.
In fact, I edited them insofar as one of their "attacks" afflicts a party member with Shield and Confuse (Stat defense ignoring), heals to full HP and raises dexterity to 255 and attack to 510 (Cloud was hit by that attack quite early and Barret finally lost the battle due to this attack). I am afraid that in this case it is close to suicidal to attempt to fight them...
Also, I wanted to use a powered-up version of these enemies in the cave of the Ancient Forest. However, as it turned out they could not be made to use summon attacks without crashing the game, I had to drop that idea. I thought of making them similar to that Conjurer you created for the area around Kalm.
Have you actually come across some of the later videos of veteran0121, the guy who published a LP of your hardcore mod? He was not too fond of your post-game changes...
(To me he seemed to be exaggerating quite a bit.)
