Fast Crystal
by LyrenXh
Fast Crystal is a client-side Fabric utility that automates End Crystal placement and detonation in PvP, with a configurable detonation delay.
What it does
Once enabled, the utility repeats the vanilla crystal-use action while the use button is held, placing End Crystals and detonating them after a delay the player sets. A settings slider runs from 0 to 500 and a toggle turns the behaviour on or off. Randomized timing is applied alongside the configured delay, so the interval between actions is not fixed.
The settings screen is reached through Mod Menu, and Cloth Config API supplies the options interface. Changes apply for the current game session, and resetting to defaults takes effect once Minecraft restarts. Fast Crystal needs Fabric Loader and Fabric API, plus Cloth Config API and Mod Menu for the in-game settings screen. It is published for 1.20.1 – 26.2 across several build groups and runs on the client only, so servers need nothing installed. The files are released under All rights reserved and the code is not open source.
Each build is matched to a Minecraft version range: builds for 1.20.1 – 1.20.6, 1.21 – 1.21.8, 1.21.9 – 1.21.11 and 26.1 – 26.1.2 are separate files, and 26.2 has its own. Installing the jar that matches the running version is required, as the mechanics depend on the game version.
Key features
Rapid crystal placement
Holding the use button repeats the vanilla End Crystal action, so crystals are placed in quick succession.
Customizable detonation delay
A slider from 0 to 500 sets how long the mod waits before detonating a placed crystal.
Randomized timing
Randomized timing is applied together with the configured delay, so actions are not spaced at a fixed interval.
Mod Menu settings screen
An enable toggle and the detonation delay slider sit in an in-game settings screen opened through Mod Menu.
