Unstable Timepiece

by Chai

Unstable Timepiece is a Fabric item that lets a player change the speed of their own time field, with trade-offs to movement, combat and hunger.

What it does

The mod adds one artifact, the Unstable Timepiece, which is crafted from four echo shards and a nether star. Holding it and using it alters the flow of time for the player, so the timepiece can speed the player up or slow them down. Each setting comes with a set of side effects: movement speed and jump height can rise sharply, while attack speed, damage taken and exhaustion can also go up, and effect duration goes down.

Because the timepiece reshapes the player's own time field, it suits players who want a cursed item that changes how a run feels rather than adding new blocks or ores. Its effects are fixed by the mod, so a server owner who wants different balance has to change the source before building. Unstable Timepiece requires Fabric API, and it runs on the Fabric loader only for Minecraft 1.21 and 1.21.1 in the 1.21 – 1.21.1 range.

The mod is released under the GNU Lesser General Public License v3.0 only, and its source code and issue tracker are public.

Key features

  1. Time field control

    Using the artifact changes the flow of time around the player, slowing it or speeding it up.

  2. Speed and jump boosts

    Some settings raise move speed by 100% and jump height by 100%, with attack speed raised by 50%.

  3. Trade-off penalties

    The same settings add 50% damage taken and 50% exhaustion, so hunger drains faster while the boosts last.

  4. Slow-time defence

    The slowed setting cuts damage taken by 50% and exhaustion by 50%, at the cost of effect duration reduced by 50%.

  5. Craftable artifact

    The Unstable Timepiece is crafted from four echo shards and a nether star, so it is reached in the mid-game.
