This mod adds the "Pomper Fist" item, an item that sends entities to the farlands! (don't take that seriously)
When obtaining the Pomper Fist, knockback X will automatically be applied to this item, otherwise it won't have it's use.
There's no plan on adding a way to get the Pomper Fist in survival. It's literally just an item made for admins on custom modded servers.
