Question about background at Leafre

I've been told that it heals you when you stand under it while it's glowing. It apparently heals a very large amount so it's rather helpful when fighting a mob in that area.

Seems like anyone who is start enough might be able to hunt down that in the wz files and alter it so that the game always thinks its glowing and always thinks the character is under it

It'd be like having godmode, but people see you take damage
