Kind’s Crystal Optimizer
by KinditMc
Kind's Crystal Optimizer is a Fabric client mod that cuts the delay players feel when placing and breaking end crystals.
What it does
Crystal placement and breaking are handled on the client, so the game responds at once instead of waiting for a server round trip. Crystal entities are hidden and rendered immediately, which keeps the visible result of each action in step with the player's input. The effect is most noticeable on connections with high ping, where delayed crystal updates are otherwise common.
The mod is a client side performance tool aimed at players in PvP and crystal-focused combat. Servers can turn it off. The player needs the mod installed, while a server may run without it, since the mod is only required on the player's side.
Files are published for Fabric only, with 17 release versions across the 1.21 – 26.3 range. The latest Fabric file is 1.6.3 for 26.3, released 2026-10-09. The code is under All rights reserved, so the mod is not open source.
Key features
Instant crystal rendering
End crystals appear on screen as soon as they are placed, without waiting for the server to confirm them.
Reduced placement delay
The gap between clicking to place a crystal and seeing it appear is shortened on the client.
Reduced break delay
Breaking a crystal removes it visually at once, so repeated hits feel more responsive.
Faster crystal interactions
Crystal entities are hidden and redrawn on the client, which keeps interactions consistent under lag.
