I know how, just change the humanoid's name, but is there a way to do it safely? Because if you do it this method, it will not allow the player the regen health! Which is a big problem. Thanks if you find a way.
EDIT
I don't want to change the humanoid's name or else I need to keep a copy of every script in the game that has "Humanoid" with a capital "H" and replace it with a lower case one.
EDIT
I don't care about this anymore, I'm moving on. I found a solution.

According to the wiki: Quickly change the Humanoid's Health from 0 to 100 and call MakeJoints on the character when it's about to die. This should prevent dying at all. It is suggested you use the Humanoid's Died event.
