Discoverable Recipes
In early releases of Sota many recipes could be added to an avatars recipe book simply by placing the correct materials onto the correct crafting bench and pressing the "Craft" button which would produce the corresponding crafted item and place the Recipe in the Avatars list of learned recipes. Over time the number of Discoverable recipes was substantially reduced until now it appears only the very high level recipes are discoverable.
