I just thought you should know, this has been around for.. years? Nothing special, don't know if it still works with stat interfaces or quest guides, but yeah.
Pppl used this a kind of a ft back then. They delayed the death, went sumwhere and just let the 0 hp kill u. When u reached 0hp you could simplly open up any interface to delay it.
Try that delay in any minigames? Prehaps make it think your in another area but your raelly in a minigame? Eg: go to CW get some bandages and when you really die you would spawn with bandages?
This is very simple and new by all means. You can control this 0hp bug in various ways. There are actually some interesting (but pretty useless) things you can do with this, like for example, at the end of a duel being presented with a screen that shows you winning against a nonexistent opponent. Hard to explain but I hope you get the idea =0.
