OptiPlus-Crystal
by CocoCC
Players who fight with end crystals can use OptiPlus-Crystal to place them without waiting on the server, since a client-side ghost appears at once after an obsidian click.
What it does
Normally a placed end crystal shows up only after the server acknowledges the click, which can make placement feel delayed or stuttery during crystal PvP. OptiPlus-Crystal places a client-side ghost crystal as soon as a valid spot is clicked, so placement feels close to single-player and no longer depends on ping. When the real server crystal arrives, it takes the ghost's place without a visible jump.
The mod is a Fabric client mod that runs on its own, so servers need nothing installed and no server-side changes are required. One jar covers the whole range of supported versions: it detects the running Minecraft version on its own, and files are published across 23 release versions. Its latest Fabric build is 2.0.3 for 26.2, in the beta channel, and the mod is released under the MIT License but is not open source.
Key features
Instant crystal ghosting
A ghost crystal appears at once on a valid obsidian click, so placement does not wait for a server reply.
Ping-independent placement
The visual result no longer depends on connection latency, since the server crystal simply replaces the ghost when it arrives.
Two disable switches
The optiplus:disable command turns off every optimization, while optiplus-crystal:disable turns off only the crystal optimization.
Server-side control
Server admins can disable OptiPlus for each player, and the flag resets when the player disconnects.
Lightweight footprint
The mod is small and needs no configuration to start working once it is dropped into the mods folder.

What the author says
OptiPlus Crystal removes the round-trip wait between clicking a block and seeing your end crystal appear. The instant you click a valid spot, a client-side "ghost" crystal is placed right away, so placement feels single-player-snappy no matter your ping. The real server crystal silently takes its place once it arrives.
