Totem_of_undying

In vanilla Minecraft the Totem of Undying cannot be crafted and is obtained only as a drop, most often by killing an Evoker during a raid or in a Woodland Mansion. A special crafting recipe in this mod lets players build a totem from costly materials like gold blocks and emerald blocks. The recipe is a three-row pattern: the top and bottom rows and the middle row each take their own inputs, and placing the items in that pattern yields one totem. The exact recipe depends on the version of the mod that is installed.

The effect of the totem is unchanged. If a player carries the totem in hand when fatal damage would land, the item is used up, the death is averted, and health returns along with brief regeneration and fire resistance. The totem disappears after use. Because it can be made, the item becomes renewable, which the author describes as useful on survival worlds and multiplayer servers where totems are otherwise hard to obtain.

The mod is published for Fabric only, for game versions 1.21.8 – 1.21.11. It is server-side only, so players join without installing it and only the server runs it. Builds are released under All rights reserved, so the mod is not open source.
