Anyone interested in crafting as many items as possible will want to grab all of the cookbooks that are scattered across the land. These cookbooks include the Nomadic Warrior Cookbooks. Nomadic Warrior’s Cookbook  will teach you how to craft Rot Pots, Rot Fat and Cord Rot Fat. In this guide we will tell you where to find this useful item in Elden Ring.
To find this cookbook, you must go to the Lake of Rot. This area is full of Scarlet which can infect and kill you very quickly. Make sure you are prepared and have given some preservative boluses before entering this area. These will help you alleviate the scarlet rot that you will definitely get.
Start at the Lake of Rot Shoreside Site of Grace and head south across the lake. You can have platforms raised by standing on the various pressure plates marked by the obelisks in the area. Keep stepping on the pressure plates and use preservative boluses when needed to avoid death. When you reach the area where the stone structures start to appear, head west. You will see a small building that you can enter. Go there and open the chest inside to get the cookbook.
