Client-Sided Crystals
by Blumbo
Crystal PvP delays caused by ping are reduced by Client-Sided Crystals, which lets players interact with End Crystals on their own side of the connection.
What it does
End Crystals are normally handled on the server, so a player's ping sets how soon the next crystal can be hit. Client-Sided Crystals moves those interactions onto the client, so a crystal can be placed or struck without waiting for a round trip to the server. The change removes the real delay on crystal interaction, which makes fights based on crystals faster for the player who has the mod.
The mod is built for Crystal PvP, where a ping-caused cooldown can decide a fight. Its features only work when it is installed on both the client and the server, so a server owner and every player on it need the mod. Players who join a server running the mod must install it as well, while a single-player world needs it on the client alone.
Client-Sided Crystals is published for Fabric only, across seven game versions 1.19 – 1.20.1, with 1.1.0-1.20 for 1.20.1 as the latest beta file. The mod is open source under the GNU Lesser General Public License v3.0 or later, and its source code and issue tracker are public.
Key features
Client-side crystal interaction
Players can interact with End Crystals on the client, independent of the connection to the server.
Reduced ping-based cooldown
The cooldown that ping normally adds between crystal hits is cut down, which speeds up crystal combat.
Faster crystal placement
Crystals can be placed and struck with less waiting for server packets to return.
Crystal PvP focus
The mod targets End Crystal fights and does not change the rest of the crystal behavior in the game.

Use cases
Who it’s for: Players who take part in Crystal PvP and server owners who run crystal-based combat. Players on a server without the mod are not covered by the change.
How it compares
Make My Crystals Faster is also a Fabric mod for End Crystals, with client and server as its environment, files for 1.20 – 26.2 and the GNU Affero General Public License v3.0 or later. No Crystal Hitbox is client-side only, uses the MIT License and covers 1.20.1 – 1.21.8, so it works without any server install. Client-Sided Crystals needs both sides, as its own environment shows.
