I used animation montages to play the animations I have at hand from mixamo, so I’ll have to dive into the animation studies sometime in order to make high quality animations at a later point of time. I didn’t figure out how do to the bone-movement or do the charge-up. I’m also trying to find a way to make melee weapons able to block eachother, but I’ll have to learn some more of the basics first. 
Hopefully someone pops by with some advice.
