Description of feature
Crafting + Usage Idea:
Smithing Table --> Bow + Enchanted Command Block Book = Command Block Bow

If you have arrows, it shoots the arrows as command block arrows, which can harm the Command Block entity in the final boss fight or trigger the WS to revive, so you don't have to go near it with a melee command block weapon. The arrows could also spawn the command block particles around them like dropped command block items do.

Maybe you could even do the same thing with a Crossbow.

This would break the final boss and make it extremely easy

actually a fair point
