You have either spent an eternity playing this game or you're using TAS.... Not a hater but how do you know where every enemy spawns in the first mission and exactly timing the spiral swords perfectly to keep them in the air😭
... how _is_ his damage so high with just the basic sword combo? I briefly played the Switch version on Easy and I did not do anywhere near as much damage with Rebellion
OK, after many extensive years playing devil may Cry, he is playing on human not demon hunter, which makes enemies super easy to kill, and a speed run consists of everything 100%, my opinion is this just a fast play through
The move is Hammer and its a move from Beowulf, you can use it by equiping swordmaster and pressing the style button while mid-air, in this video he's jump cancelling that move.
