PiggyCrates is a simple, customizable, crates plugin. It supports an unlimited amount of crate types. It also supports vanilla and custom enchants, such as PiggyCustomEnchants.
How To Use
Place a chest on top of a designated crate type block to create a crate.
To open crates, you must use a crate key, obtainable with the /key [amount] [player] command.
If you want to give everyone in the server a key, you can do /keyall [amount].
This plugin is awesome, however.. I recommend adding the availability to see the keys IDs in the config.
It would be nice to be able to put keys inside crates. For example:
A uncommon key as a reward inside a common crate.
