I've already seen the videos for inertia and sky guarding, and although i have the practical knowledge to pull it off, i would want to understand how the mechanics work too. So, what exactly happens when i JC Killer Bee and use guard to give a direction to the inertial movement? In my head, the jump-cancel would cancel the inertia because Dante stops for a moment and change his trajectory upwards for an instant when you jump-cancel, so i really don't know exactly how the game sustains the inertia from the Killer Bee if i stopped and even changed the trajectory while this initial inertial movment was conserved and use to move quickly to another place; i think if we could break this mechanic out we could think about different and more subtle usages to inertia, if someone else not already accomplished this with different movements.
EDIT: How do people cancel High Roller without even leaving the ground? I've seen plenty of people doing this in combo videos but i don't tried to find an answer until now.
Thanks in advance, don't mind if i take some time to read the answers here, but be sure that i'll read them
