Clay is a crucial resource in Windrose for crafting clay bottles for potions. It can be found in large deposits of muddy rock scattered across the terrain, which are exposed and easy to identify. Clearing a single deposit yields about 50-60 chunks of clay. A pickaxe is necessary for harvesting clay, with recipes for a Stone Pickaxe requiring 3 Stone and 3 Wood, and a Copper Pickaxe requiring 1 Bronze Ingot and 5 Wood. Upgrading tools does not affect yield but can speed up the harvesting process. Clay deposits respawn every few in-game days, and crafting a clay bottle requires one chunk of clay, but the bottles are not reusable. Resources can deplete quickly, especially when dealing with wild boars.
