Amethyst

Amethyst is a rare ore used to upgrade your Portal or create an Amethyst Pickaxe. The Amethyst is a fairly common gem found in caves which emits a small amount of dim light for a few blocks.

Uses
The Amethyst is used to craft:

-The Amethyst upgrade at the portal (1 amethyst, 20 Time Crystals);

-Amethyst Pickaxe (5 Amethysts, 20 Time Crystals);

-Amesthyst Chandeler (5 Glass, 10 Amethysts);

Obtaining
Amethysts are fairly common and can easily be found in a cave. They appear to be floating when first seen and can be mined as you would pick up an item, it will then make a loud chime noise. Amethysts can also be obtained using a Gold Pickaxe on rocks, such as Stone and Limestone.
