About this project
What does Upgrade Crystalline - Amethyst Expansion add?
Upgrade Crystalline adds plenty of building blocks, utility items and overral functionality.
Amethyst Sack

An item that opens a chest-like GUI on right click, that has 5 slots to put items in. It is crafted with 1 Amethyst Shard, 2 Amethyst Fragments, 1 leather and 1 string.


Amethyst Hammer
Provides New Utility for Farming and Building. If you right click an Amethyst Block, it turns into Budding Amethyst, but wastes 15 uses of this tool. If you right click a block that has a Cracked Variant, it gets replaced with it instantly. This action deals 1 damage to the hammer.

Craft it with 1 Stick and 4 Amethyst Shards.
Amethyst Fragment
These are used for crafting other items.


Amethyst Boots
These greatly increases your friction on slippery blocks, letting you traverse iced biomes faster without boats. Craft it using 4 Amethyst Shards and 2 Iron nuggets.


Amethyst Dust
Used for making purple dye.


Amethyst Blocks
Added Polished Amethyst Blocks and Amethyst Bricks

Amethyst Bulb
A new block that emits light. Craft it using 4 Amethyst Shards, 4 Amethyst Fragments and a Lantern.
