Crafting the Amethyst Armour set & Tools:
To craft amethyst armour and tools use Amethyst Shards in the crafting table, like you would with any other armour and tool set.

Reinforcing Amethyst Armour & Tools:
- Find Red Emerald Ore and mine it. This can be found in the overworld from y = 40 to y = -64 (very rare) and in the Big Red Forest Dimension from y = 50 to y = -64 (rare).

- If you smelt Red Emeralds you get a Red Emerald Ingot.

- When mined with a pickaxe of iron level (or better, i.e diamond, netherite, amethyst, reeinforced amethyst) it will drop a Red Emerald.

- Then you can use this ingot in the Smithing Table to make Reinforced Amethyst Tools and Armour.

Note: Reinforced Amethyst Tools and Armour are better than Netherite and can be repaired using a Red Emerald Ingot.
