Sulfur Cube Club

A weapon version of the Sulfur Cube. (the name Sulfur Club Cube is too long and there's a word count so it's just the Clube from now on.)

You can load blocks into the Clube to change the weapon's properties based on the block's archetype, and you can swap these blocks out whenever you want. On top of that you can load up to 3 blocks into the Clube to mix and match their different properties.

Using a slime block will basically it Knockback while doing very little damage in exchange. Using a blocks of ore/metal will increase it's damage but make the weapon very slow. You could use ore and slime blocks together to get both Knockback and a regular amount of damage, or you could use 3 slime blocks to do the maximum amount of Knockback possible and send mobs flying, or use 3 ore blocks and make a very high damage weapon that you basically only get 1 swing out of due to how slow it is.
