Glisining Ore

Players have always wanted a 6th tier of Enchantments for some reason but what if we add that in an interesting way and also make it based on luck: Glisining ore is an inherently enchanted material that can be found in moderately deep caves. When combined with iron and then smelted one can create a sort of Glisining alloy that can be turned into enchanted tools. When Glisining tools are created they are randomly enchanted with any vanilla enchantment between the levels of 1 and 5 that is applicable to them. This can go over the enchantments normal level cap.
