short video, got someone else to record it because it looks different on their screen than mine, dunno if it's known, but there was only another vid on youtube and it was uploaded 2 days ago.
basically if you get on your demon slayer mount, and use the /dark force command while wearing the dark force set, you'll end up like the above vid, people who were with you on the map will see you like if you had no wings (this is how you see yourself) and new people that enter will see you with the wings.
you can do all attacks and everything, you just pretty much have 190% speed, which is not useful at all for a demon slayer, i wonder if you can do it with other mounts, and how'd that look lol. probably possible on any class?
thanks @icephoenix21; for recording it for me.
