Alright. This looks beautiful. A casting animation/posture while using spells is always very welcome for me. Nevermind that you dont just use a standard casting animation for each spell (You yourself got that dark whirlpool while the skeletons got that arcane sign thingy). That is really good. Also you forgot to change it into english given that most on this site speak english it would probably be better to do so, even if this is just to show of animations. (German is my first language so i really dont mind just general advice)

Though that magic is weaker then a normal attack, if this stays like that (which i admit is unlikely), is kinda stupid. Especially if you hit the weakness. I mean a normal attack (that doesnt use ressources) did 16-18 while a magic spell did 11 which hit a weakness is just wrong.

I might think so because i favor mages, but spells should have an impact proportional to the ressource used. You just used a spell you can use what? 6 times? That did around 30-40% less than a normal attack? Thats just wrong.

But apart from that it looks very beautiful. Have a nice day!

Edit: Maybe have status effects be inflicted by normal attack spells like a burning effect from the flame. That would go a long way to make it more useful if the damage stays close to the same.
