Archaeology

Archaeology is a custom enchantment that can be bought from Toolsmith or Beastmaster shopkeepers. By breaking stone or deepslate, you may find Ancient Shale or Relic Shards. The cooldown on this chance goes down with each successive level of Archaeologist on the tool, and starts at around 5 minutes. Certain fossils may be obtained from assembling fossil parts, and Medium and Large fossils award 2 and 3 SoxBux respectively upon completion.

Additionally, there are two Archaeology pets: the Compsognathus and the Amber Dragonfly. They're made out of old and they can be your best friend.

Relics
In addition to Fossils, there are relics obtained from Relic Shards. Known relics include:
