I just passed 400 hours lol. If you want to start combo-making a good way is to look at others combos simple or not and try to mimic it. Also, putting yourself in awkward situations and trying your hardest to see how you can continue tge string works well. Theres lots of tech to learn as well but keep it simple to start. You can see sone if mt early dante and vergil combos on my channel and well, they look a bit sloppy now :/ but ive improved a lot just by continuing to try. Its a long but fun process, and i wish you luck
