This simple script gives mobs a 10% chance to have a positive potion effect when spawned naturally.
You can change the chance for mobs to spawn with effects using "/chance" or "/rme:chance", ranging between 0 and 100.
You can also modify the script file to change what effects are applied, and what mobs can receive them. Feel free to use this in whatever.
