Tomb Many Graves Mod for Minecarft 1.9.4 Mods adds just one block: a grave. You can’t craft it, you can’t harvest it, but it’s important. Upon a player’s death (assuming you haven’t disabled graves in the configs, but if you do that why did you install the mod?), a grave block will be spawned that contains all of the dying player’s inventory (including Baubles) and a chat message telling you the exact location of the spawned grave will be given to you.
