Crystal helper
by tgyki
Crystal helper shows, while a player holds an end crystal, where a crystal placement would land well, risky or poorly in combat.
What it does
The mod marks the block a player is looking at with a colored outline, so placement quality is visible before a crystal goes down. It only activates while an end crystal is held, and it outlines only the block currently being targeted. Three colors separate the outcomes: a placement that deals high damage with minimal risk to the player, a risky placement where both sides take heavy damage, and a poor placement that does little damage or can backfire.
The mod is aimed at players learning end crystal PvP who want to make more informed placement decisions in real fights. The detection and colors can be set in the configuration, including a HUD option. Crystal helper is a client mod, so only the player's game needs it, and its settings screen is opened through a separate configuration menu. The mod is published for Fabric only, for the 1.21 – 1.21.8 range, with 1.21.8 as the latest file. It is released under All rights reserved, so it is not open source.
Key features
Strong placement outline
A colored outline marks a block where a crystal would deal high damage with minimal risk to the player.
Risky and poor placement colors
Separate colors flag placements that hurt the opponent and the player, and placements that deal little damage.
Targeted block only
Only the block the player is actively looking at receives an outline, so the screen stays uncluttered.
