This uses unlocked boss character to speed up the run, i will still try 2 more characters, but i don't have any hope they're better than lillymon or duskmon EDIT: Gabumon became faster than lillymon lol

For character exclusive mechanics, you can short hop and teleport repeatedly with duskmon to cause damage and reposition yourself the only problem it's actually RANDOM where he spawns, he usually tracks enemies or items, but the more enemies you have the less consistent you can repeated teleport. You also need to touch the floor again to reuse your moves and that includes the teleport.
