A second character

Hey everyone! Hope your day is going great! If you've seen one of my previous posts you might know I'm a darius main, and I've started trying to improve on my gameplay with only him, so now I'm only really "good" with my newly learned mechanics on him. But darius, for my elo, is a more common ban, so I wanted to learn a champion that has a higher skill cap.

And I found fiora. It might be a bad idea, but does anyone know how I can put my newly learned mechanics I learned on Darius into my Fiora gameplay? I've learned things such as CS (as in around 10 per minute) learning how to outplay and pressure others out of lane, playing safe, etc. How can I put things I've learned on Darius onto Fiora? I'll probably have to play alot more Fiora and learn her kit and stuff, but I hope this made a bit of sense. Thank you for reading!
