An AngelChest.

An AngelChest will spawn on your place of death. Teleporting to an AngelChest costs ₪40.

When you right-click the AngelChest, your inventory will be restored. If not all items can fit in your inventory (because you picked something up after respawning), the remaining items will be left in the chest and you can decide which items you want to leave behind. Once the chest is emptied or the duration is reached, it will despawn and drop the remaining items.
