The Mace is a heavy weapon that deals 7 points of damage to any entity. It can be used to hit creatures by falling from a high place to produce more damage, but there are a lot of implausible factors involved.

For example, if you spawn a Creeper in the fence, then stand 100 blocks away from it, at the same height as the Creeper, prepare the Elytra and fireworks, double-click on the spacebar with the fireworks and fly towards the Creeper quickly, and then hammer down on it, it can only do 7 points of damage, which is obviously unreasonable, and the damage of the Mace should be affected by both height and speed!
