A life boots armor is required to trigger this bug. The higher the level of life boots, the higher the HP after triggering this bug.

First of all, you need to prepare an ordinary armor. In the same map, three lives are exhausted. When the last death interface appears (see "1. PNG"), the bug will be triggered when you replace the armor with life boots in the item list. (see "2. PNG")

 
This bug can be used in multiplayer games, and other players can't detect it when using it, which affects the game balance. Hope to fix it as soon as possible, thanks
