How do I make something so if a player does something it does 1 damage to that player.
Like you know the cave thing under lumbridge, if you go in without a light, you get attacked 1 damage every time.
I just need it to do 1 damage to the player, and ONLY 1. It never changed, NEVER 2, 3 ,4 anything, just 1!

So does anyone know how to do it?
