Crystal Insight
by ByJam
Crystal Insight is a Fabric combat overlay for crystal PvP practice that shows block exposure and damage figures on the HUD.
What it does
When a player looks at a block, the overlay reports the explosion damage a crystal placed there would deal, along with exposure and armor damage figures for nearby targets. The aim is to let a player test crystal placement positions during practice rather than in live fights. After each kill, a summary reports consistency, combat efficiency, damage reliability and suggested areas to improve.
The tool never places crystals, breaks blocks, attacks players, changes the hotbar or moves the camera. Every action stays with the player, so it is meant for solo training and does not automate a fight. Crystal Insight runs on Fabric for 1.21.11 only, and it is client-side only, so it is installed on the player's game and not on the server. It is all rights reserved and not open source.
Key features
Explosion damage overlay
The HUD shows the explosion damage a crystal would cause at the block the player is looking at.
Exposure and armor readout
Exposure and armor damage figures are displayed for targets near the placement positions under study.
Post-kill summary
After a kill, a summary reports consistency, combat efficiency, damage reliability and recommended improvements.
Training only, no automation
The mod never places crystals, breaks blocks, attacks, changes the hotbar or moves the camera.

Use cases
Practicing crystal placement
A player can check how much damage a position would deal before committing to a real fight.
Checking a session
The summary after each kill helps a player see where their timing or positioning lost value.
Who it’s for: Players who practice crystal PvP alone and want numbers on placement and reliability. The overlay does not play for anyone, so it fits training rather than competitive use in matches.
How it compares
PVP essentials Refined is open source under the MIT License and is published for 1.21.10 – 1.21.11, so it covers a slightly wider span than this mod. Crystal helper is also client-side only, but its files target 1.21 – 1.21.8 and it is all rights reserved. Arrow Helper is client-side only for 1.21.11 alone, and NoCrystalPVP is server-side only, so a player needs nothing installed to join.
