For those who are having difficulty dealing with the puellas from this beautiful creation and uninstalling the mod out of pure rage, it's actually quite simple to deal with these enemy weebs with 4 different methods:

Puellas are a peculiar enemies, very low in health (2-3 hp) and potent in strength and defense (Glass cannon what it should be but I see it as Mobile Psionic Platform) with the unique trait of using annoying wishes in battle and being one of the most annoying female enemies I've ever faced compared to my sister lol, (but seriously it's sad to see a little girl handle a sectopod calmly and almost exterminate a ruler or avatar by itself, very well balanced) and they use "overdrive" immediately upon encountering an enemy and cast 3 random psionic abilities from their arsenal on nearby enemies, the most opportune moment is during the cooldown of their abilities

-Always take a stealth soldier like Reapers or classes that prioritize camouflage (highly recommended)

- skills with guaranteed damage like the "combat protocol" (if it goes through over heal health, shield and armor even better)

-Soldiers with ridiculously accurate aim are essential (this mod makes any miss a pure sin, and never use overwatch with soldiers that have low or medium aim, seriously if you want to suffer disobey me and stay on the loading screen for more than 15 minutes after a guaranteed restart ;)

-And the most powerful weaponry: Psionics, the puella magi class mod for "absolute no reason" is very effective against other puella who could imagine, also also soulfire and null lance are very effective ( Spoiler: note that puellas on the wish effect of " Psi Dopping" are almost invulnerable: 5 to 6 points of armor, immune to negative mental effects, and I think it reduces the psionic damage received too, but it only has 2-3 health so I don't know if it's true :D )
