This plugin allows high ping players to crystal quickly by processing the left/right clicks as the packets come in. This means that the server does not have to rely on the client's attack packet to destroy a crystal, and also does not have to rely on the client's block interact packet to place a crystal. This is the main reason why high ping players cannot crystal quickly normally; the crystals take too long to get destroyed/placed on their clients.
The plugin will only function on Paper (or its compatible forks) and Folia servers.
PacketEvents must be installed for this plugin to work.
