Slowness Gamble
by raskajanie
Slowness Gamble is a Fabric challenge mod in which a time break block can make the player slower for a while, with the chance tuned in the config menu.
What it does
Each time break block carries a random chance of reducing the player's movement speed, so stepping into one may leave the character moving like a snail. Whether a slowdown happens depends on the luck chance set in the options, and its strength follows the slowness intensity setting.
The mod is aimed at players who enjoy consequences that come from chance, and it suits solo play as well as adventure maps. Turning the mod off in the settings restores the original speed immediately, so a bad streak can be ended without restarting the world. Adjusting the luck chance and slowness intensity needs Mod Menu and Cloth Config, which give the in-game settings screen.
Slowness Gamble requires Fabric API and Cloth Config API. Mod Menu is optional but needed to reach the settings. Players must run the mod on their client, while a server can skip it and still host the game. The mod is released under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license and is not open source. Files exist for 1.20.1 and 1.21.1.
Key features

Slowness intensity
A separate setting controls how strong the slowdown is, from mild to close to a crawl.
Instant restore
Disabling the mod in the settings returns the original movement speed at once.

How it compares
LegacyRoulette is a Fabric mod for 1.21.5 – 1.21.11, client-side only and under All rights reserved, so it does not target the versions this mod covers. Gambled is a Fabric mod for 1.20.1 that needs both client and server, and is also released under All rights reserved. Speed FOV Limiter is open source under the MIT License, client-side only, and built for 1.20 – 26.3, so it covers a different chance mechanic and other versions.
