Crystal Optimizer Mod is an optimization mod that eliminates server lag after breaking crystals by instantly breaking your end crystals on the client side, resulting in faster crystal speeds. You might not notice an immediate difference, but it significantly enhances performance, especially on laggy servers (80+ ms ping).

How it works:
- The reason for this? Usually, when breaking a crystal, you must wait for the server to return that the crystal was removed before placing another crystal in that spot. The optimizer skips that requirement and actually eliminates the end crystal entity right when you break it. This mod heavily reduces the effect ping/server lag has on crystalling.
- If you want to take it a step further, bind the place block to a key. Because of the key repeat feature on most devices, holding the key will repeat itself at an extremely high rate.

Installation Note:
