If I add a skin to the tools, can I add them to the loot table as an item? Meaning if they are set to have that skin, will they drop as an enchanted tool? Or will they just be a tool with a skin?

The plugin currently sets the item with a hash and it checks if the item has that hash. I could change it to be by skin if need be and just add a configuration option.
As for now the item has to have been spawned in via command.

Understood. Thank you for your response.
