Ambrosium Shard (The Aether)

Ambrosium Shards are obtained by mining Ambrosium Ore found all around in the Aether Dimension.

Sometimes, Ambrosium Shards are found as a reward in chests after a boss battle in Bronze Dungeons and Silver Dungeons.

The Ambrosium Shard can be mined with a Holystone, Zanite, or Gravitite pickaxe.
