So basically all you have to do is select any characters that has Daisy's statistics.
Once you've done that you need to always inward drift and while you inward drift in a direction, press break to go on the opposite side of where your character is looking (it's basically like snaking but way more fluent, way faster and you can choose which direction you always wanna go).

Ok Thanks Nodac!
