Root motion or script motion to make a character like riven? and any suggestions for learning resources

My problem is that I want to make a character that is very similar to riven in particular I want help on how to make her q ability since I t$$anonymous$$nk that if I understand that a lot of the other stuff will make sense.

T$$anonymous$$s is a video showing her abilities you can see what I want to do from t$$anonymous$$s

In particular my problem is with the animations(I know how to make the animation) and the collides. Im not sure if I should be using root motion or script motion to move the characters since using root motion seems like a better idea because it will allow me to just use the animations to move the character through the q animation without having to script anyt$$anonymous$$ng and if i was using script motion I have no idea how im supposed to move the character through the q animation since the animations would be in-place. I was t$$anonymous$$nking that t$$anonymous$$s could be solved by using both script motion and root motion but from what i know you can only use on at a time and not both together

I am also unsure as to how im supposed to handle collision with root motion and scripting since I would have to use multiple colliders on different parts of the body however to my knowledge t$$anonymous$$s is very inefficient and i notice most people just use a capsule collider instead so im not sure if I just wasnt looking at the right stuff or if im missing somet$$anonymous$$ng.

so to summarise I want a solution that will allow me to have a character like riven with accurate $$anonymous$$t boxes(if using multiple $$anonymous$$tboxes instead of a capsule collider is the right way) that is very responsive.

Im very new to unity so I would appreciate any help since I have already spent more than 2 days trying to find out how to do t$$anonymous$$s with no progress so if you can point me to any tutorials that can help me ac$$anonymous$$eve t$$anonymous$$s or if you know anyt$$anonymous$$ng about t$$anonymous$$s I would be really grateful for your help.

Thank You
