Make the heavy core like a stronger anvil

The heavy core should have gravity and deal damage to players like the anvil. Similar to the mace, it will deal more damage the longer it falls. Basically just a block version of the mace. Could be good for traps, and other stuff.

EDIT: Something I forgot to mention was balancing, due to the fact this removes the entire risk factor of the mace, I have come up with a proposed solution:

Every time the mace falls, it has a chance of breaking and being completely destroyed. The farther down it falls, the higher the chance. That way there is still a risk factor when using it.

If you want to guarantee land a hit on something, use the core block itself. Risk of not being able to use it again

Want to guarantee keeping your mace, use the weapon itself. Risk of dying
