Memorial Tag

Memorial Tag adds a small but meaningful recovery system for named mobs and owned creatures.

When a living entity dies, it may drop a Memorial Tag if it has a custom name or an owner. The tag records the entity's identity, name, type, cause of death, and the world day on which it died. A backup of the entity's NBT data is also saved in the world save folder.

The tag can later be used together with a Totem of Undying to bring the creature back.

Features

Named mobs and owned entities can drop a Memorial Tag on death
The tag stores the entity UUID, entity type, displayed name, death message, and death day
Entity NBT is saved under the world save folder
Use a Memorial Tag together with a Totem of Undying on a block to respawn the entity
The revived entity receives a new UUID to avoid UUID collision
Memorial Tag item names show the recorded entity name
Tooltip displays the cause of death and how many days ago the entity died

Usage

When a named or owned non-player living entity dies, it drops a Memorial Tag.

To revive the entity:

Hold the Memorial Tag in one hand
Hold a Totem of Undying in the other hand
Right-click a block
The entity will be restored near the clicked block

Both the Memorial Tag and the Totem of Undying are consumed, unless the player is in creative mode.

Notes

This mod is mainly designed for pets, named companions, and other mobs that players may want to preserve. It does not generate Memorial Tags for players.

The restored entity is recreated from saved NBT data, but some volatile data is intentionally removed during restoration, such as the original UUID, health, carried inventory, and hand items. This helps avoid entity duplication issues and UUID conflicts.
