The rewards should have NBT tags available. In the rewards file, it should be written in text, similarly to how NBT tags are specified in commands.

• NBT Tag written in JSON format in the config files :

{
    "item": "minecraft:diamond_pickaxe",
    "count": 1,
    "metadata": 0,
    "tag": {"Enchantments":[{"id":"minecraft:fortune","lvl":3}]}
}

• Better tooltip for the rewards : all tooltips shown except tool modifiers.
