Enchanted amethyst crystals for Kaleidoscopes, potions and enchanting

Enchanted Amethyst crystals:

When breaking an amethyst bud, there is a 5% chance it will drop an enchanted amethyst crystal. This can be used to craft other items.

Kaleidoscopes:

Kaleidoscopes can be crafted with 2 copper ingots in the middle and one enchanted amethyst crystal on top, (like crafting a spyglass but with enchanted amethyst instead of regular amethyst). This can used to view your world in a trippy kaleidoscope fashion.

Potions:

The enchanted amethyst crystal can be used to craft a potion of resistance. This potion will give you resistance against almost all bad effects like poison or wither. 

Enchantments:

You can combine one enchanted item with an enchanted amethyst crystal in a smithing table to increase the enchanted items enchantment level. Example: Sword with sharpness IV + Enchanted amethyst crystal = Sword with sharpness V. If the item has multiple enchantments you need to use multiple enchanted amethyst crystals.
