keepinv:gravehold
Gravehold is a chestplate enchantment from the Nice Keep Inventory data pack that doubles the duration before dropped items and generated graves despawn after death.
The enchantment can be obtained from Loot Sources using the Enchanting Tables, Random Loot, Traded Books & Treasure tag lists.
If a player dies while wearing a Chestplate enchanted with Gravehold, the lifespan of dropped items and generated graves is doubled before they despawn.
Gravehold cannot be combined with the other enchantments from the Nice Keep Inventory data pack: Safekeep and Deathlock.
