About this project

What does OptiPlus-Crystal add?

💎 OptiPlus Crystal

Zero-wait end crystal placement — now on Minecraft 1.20 through 26.2

What it does

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.

No more waiting on the server to acknowledge your click, and no stuttery placement loops during crystal PvP.

Features

Instant, ping-independent end crystal placement
Client-side only — works on any server, nothing needed server-side
One jar for every version — it auto-detects your Minecraft version and just works
Lightweight, Fabric

Supported versions

A single jar now runs on Minecraft 1.20 → 26.2: 1.20, 1.20.1–1.20.6, 1.21–1.21.11, 26.1 and 26.2 (Fabric, client-side). Just drop it into your mods folder.
