If you die with a renamed item enchanted with Curse of Vanishing, it will just say "Vanishing." since the word "Vanishing" can't be enchanted.
Curse of Vanishing is a very situational enchantment, especially when found on something valuable such as diamond ore or the Nether Star.
There are many enchantments you can give to weapons and armor in Minecraft in order to protect you from various sources of danger. However, some of them are more difficult to find or expensive to buy. Finding an enchanted diamond sword might cost you an arm and a leg (in-game, obviously!).
So, if you don’t want to buy it but still want to be protected, there’s an enchantment for that: the Curse of Vanishing enchantment is one of the most useful ones!
Curse of Vanishing is notable for being the first enchantment added by a mod that was implemented into vanilla Minecraft. Some consider the Curse of Vanishing overpowered or even broken, as it is possible to become highly armored and equipped with strong weapons without consequences.
This enchantment can be applied to Bows, Swords, Pickaxes, Shovels and Axes so that they drop as a half-heart on death.
When the player dies while an item enchanted with Curse of Vanishing is in their inventory, Enchantment Descriptions, Particle Effects and Unbreaking are removed.
This makes the enchanted item at the minimum more powerful than diamond armor, equivalent to iron armor without enchantments, but not separating it into two pieces when it is destroyed. To counter this, some players simply keep another piece of leather on them as a replacement should their current piece of enchanted armor break.
The enchantment completely changes the way you play Minecraft, forcing you to choose between risking death with your powerful weapon or taking the time to replace it and leaving yourself vulnerable in the process.
Curse of Vanishing is a pretty useful enchantment in Minecraft.
Essentially, this enchantment makes it so that when armor lets you take damage, it also reduces the durability of the armor by the same amount.
It’s definitely worth having on certain items, such as most types of chainmail items or leather armor, for example. The problem is that this enchantment has a maximum level of 1 — so once you get Curse of Vanishing I and nothing higher.
The curse of the vanishing enchantment will allow you to trade with a villager, but upon trading with him/her and the trade window disappearing, the villager will automatically die.
Some players like this enchantment as it allows them to kill hostile mobs without having to get closer. However, they usually don’t know that they have to trade the enchanted item before they can kill the enemy mob.
The only way to remove the curse of vanishing from a single item is to place that item into a chest and then remove it via an Ender Chest. The cursed item will disappear and the Ender Chest will retain the enchanted item.
