I made a mod that adds Amethyst tools that can be upgraded from Netherite tools.

This mod introduces four specialized tools—Axe, Pickaxe, Shovel, and Hoe—that retain Netherite's base stats while gaining unique abilities.

Core Features

• Amethyst Shovel & Pickaxe: Mines in a 3×3 area.
• Amethyst Hoe: Harvest, replant, and till in 3×3 areas with a single action.
• Amethyst Axe: High-precision tree felling that clears entire trees while strictly avoiding nearby player builds.

Amethyst Energy System

Each tool features a dedicated 3000-point Amethyst Charge, independent of its standard durability. Using Amethyst effects consumes this energy, causing the tool to revert to a standard Netherite state upon depletion. Recharging is achieved through Amethyst Clusters, merging tools, or via a Mending enchatment.

The Evolution Ritual

Creation requires more than just crafting; it requires a ritual. Deep within an Amethyst Geode, you must harness a Beacon's light to forge your tools. This is not a simple placement of items, but a trial of optics and geometry:

• Manipulate the Light: Use various growth stages of Amethyst to reflect, refract, and extend the beam.
• A Seed-Based Puzzle: The path to evolution is unique to your world. You must find the exact sequence of reflections required by your specific coordinates and world seed.
• Visual Alignment: Watch the beam’s color shift as it nears the correct frequency. Only a pure white light, maintained for a steady 10 seconds, has the power to transform Netherite into something far more mystical.
