Full list of changes in this patch:

Delve into a strange cave with a seemingly endless supply of treasure, strategically choosing your battles to gather as much treasure as possible! Find rare artifacts and traverse the skill tree to become your choice of a mage, warrior, alchemist, or a mix of skills. Craft potions or enchant your equipment with ingredients, and discover secret areas! But be careful because the cave has oddly become quite dangerous lately with more explorers going missing every day…
