Yapi: Forgotten Echoes

Supported equipment that would normally despawn after expiring on the ground is saved to a per-world storage instead of being lost. Stored items keep their original data, and later compatible mob spawns have a small chance to equip a mob with one of them. Yapi: Forgotten Echoes keeps gear from its own world rather than inventing anything new: no added items, blocks, mobs or dimensions, so losing an item carries a modest cost without filling the map with fresh loot.

Default rules cover mobs that normally hold and use equipment, and only items matching the configured rules are eligible. Per-dimension storage is the default, and the behavior can be changed in the config. Additional melee item IDs can be added manually there, and modded equipment works like normal Minecraft equipment. Returned gear has reduced drop chances by default, and a rare default rate of 0.5% for compatible mobs sets how often forgotten equipment appears. Players who want old gear to affect later encounters, on survival worlds and long-running servers, will find this most relevant.

Yapi: Forgotten Echoes runs on the server alone, so players join without installing it. It is published for Forge and 1.20.1 only, with 1.1.0 as the latest file from 2026-05-28, and is released under the MIT License, which is not an open source license.
