I;m not sure, but I feel like there might had been an oversight. Usually when certain enemies use spells they tend to have the name of One spell but the animation of another (ex. Voidsent have Void Fire II which has Flare's animation and Void Blizzard II with Freeze's animation, though this is not always the case) And the Ixali bosses of Xelphatol have their verison of Aero II and III with different animations, effects and most importantly names...

However Sophia has attacks named Aero II, Thunder II and Thunder III, despite being visualy and mechanic different from the player version of these spells (the former has Aero III's animation in additon to being point blank and having knockback, the middle is a cleave and the latter is a donut shape AoE, not to mention that none of them have DoT components)

I want to know if them sharing the exact same names with Thunders II and II and Aero II is intentional (and if I made mistake about Sophia's Aero II for soemthing else please let me know)
