enchantencore:blindness_curse
#minecraft:on_mob_spawn_equipment#minecraft:on_random_loot#minecraft:treasure#minecraft:curse
A curse that permanently blinds the wearer. Every 5 seconds the wearer receives Blindness II for 7 seconds, so the effect never runs out while the helmet is worn.
As a curse, it cannot be removed with a Grindstone and shows up in red on the item.
This enchantment has an anvil cost multiplier of 4. When combining it from an enchanted book, the cost is halved.
