If you have an idea for an item effect, suggest it on GitHub!

A lot of modded items should work out-of-the-box, including tools, melee weapons, foods, blocks, spawn eggs, mob buckets, minecarts, and boats.

Multichambered

Multichambered lets you load multiple shots and fire them one by one, like a revolver. Crouch and use a crossbow to load additional shots when loaded, and use normally to fire. You can load different types of ammo, and the first item you load will be the first item you shoot (so in terms of data structures it's a queue not a stack).

Multichambered has a max level of 3 (III) and is incompatible with Multishot and Quick Charge.

Compat

If Enchancement is installed, Multichambered will be removed and Omni or Scatter will also act as Multichambered III.

Crossbow Scoping works with Omni and Multichambered.

Under Enchiridion, Omni is categorized as primary and Multichambered is categorized as secondary.
