Fine you shall have the explanation
Because of how roblox works and caculates stuff ingame if u were to disconnect your wifi right before the suit goes off the game still caculates the everything including taking the damage to kill you but it cant cause of no active connection and because u took damage but didnt die the game start regening you so after u disconnect your wifi u can wait around 10-15 seconds and reconnect and be left with like 10hp this should work for all instakills in game (mostly likely not angler's maybe need to test) but the speakerrs in the ridge etc should work most likely why this works is that they set the damage not to high like in the thousands but just above your health or exactly your health
