Crystal PvP ("cpvp") has become a pretty popular combat mode in Minecraft. Crystals themselves were never designed to be used in combat. Because of this, a client ping (latency) plays a significant role in a crystal PvP fight, affecting how fast you can spam. This mod helps to reduce (but does NOT fully remove) the ping factor from crystal PvP fights. This is commonly called a client-side crystal optimizer mod. It also removes the ping factor for PvP with anchors, though the ping doesn't play a big role in anchor fights, and it might even be beneficial to have high ping in these fights. This is not the only crystal optimizer mod available, but it's the most configurable out there.
NOTE: A server-side crystal optimizer plugin (not this mod) is much more
effective. Consider checking the /fastcrystals command or similar commands
on your server. Ask the admins to install one if the command doesn't exist.

Q: I need help, have some questions, or have some other feedback.
A: You can join the Discord server.
Q: Where can I download this mod?
A: Modrinth
or GitHub Releases.
You can also find unstable builds at
GitHub Actions.
You'll need a GitHub account to download these.
Q: Which mod loaders are supported?
A: Fabric, Forge, and NeoForge are supported. Quilt should work too.
Q: Which Minecraft versions are/were supported?
A: See the "Versions" section.
Q: Why support so many Minecraft versions?
A: Because I can.
Q: Do I need Fabric API or Quilt Standard Libraries?
A: Yes, you'll need Fabric API for Fabric and QFAPI/QSL for Quilt.
Obviously, you don't need them for Forge or NeoForge.
Q: Is this mod client-side or server-side?
A: This mod works on the client side. There is no server-side version.
Q: Is this a hack?
A: It depends on your opinion on what's a hack and what's
not. This mod reduces the role that ping (latency) plays in
combat with crystals. Specifically, it does affect how fast
the crystals are removed. Crystal placement is NOT affected.
It cannot be affected in a way that's considered legitimate.
Q: Is this designed to be a hack?
A: No.
Q: I've found a bug.
A: Report it here. If you are not
sure whether this is a bug or a simple question, you can join the
Discord. Report security vulnerabilities
here.
Q: Can I use this in my modpack?
A: Sure. Credit (e.g., a link to the mod's GitHub page) is appreciated but
is not required. Monetization and redistribution are allowed as per the
Apache 2.0 License.
BEWARE: This mod may be considered a hack by some people.
Q: Why does this mod exist, when there are server-side crystal optimizers?
Is it better than other client-side crystal optimizers (alternatives)?
A: Firstly, this mod was created in 2023 before the server-side crystal
optimizers. Secondly, not every server has a server-side crystal optimizer.
Thirdly, I updated it in 2025 because I needed to learn the
Stonecutter preprocessor.
Now it's not hard to maintain, so why not. It is probably
neither better nor worse than other client-side crystal
optimizers, but it has a lot of settings for your convenience.
Q: How fast is it?
A: It should be pretty fast. No precise numbers,
it depends on the ping, server MSPT, etc.
