Final answer:
The maximum level for the Curse of Vanishing enchantment is Level I, and it causes items to disappear when the player dies.
Step-by-step explanation:
The maximum level for the enchantment Curse of Vanishing is Level I. This means that there is only one level for this enchantment, and it cannot be increased through any means in the game. The Curse of Vanishing enchantment can be applied to any tool, weapon, or piece of armor.
When an item is enchanted with Curse of Vanishing and the player holding it dies, the item will disappear instead of dropping on the ground. This can be particularly definitive in PvP (Player versus Player) situations, or to prevent other players from obtaining your items upon death.
