Arcane Shard
Used for most of the crafting recipes in the mod. Found from y=8 up to y=38 in the form of Arcane Ore, which requires iron tools to mine.
Sheet Stone
Found in large patches all over the world, it can be used for crafting or building.

Crafted from Arcane shards, Shardtools and Shardarmor are similar to iron tools and armor, but slightly different.
Cleansed Flesh
