Where is the Nomadic Warrior’s Cookbook 22?
You will need to travel to the Lake of Rot, which is infamous for Scarlet Rot, in order to find Nomadic Warrior’s Cookbook . Unless you have some consumables that can protect you, such as Preserving Boluses, you should be cautious of red clouds that can cause damage to build up over time.
You will greatly benefit from them before entering this area as they will greatly minimize the damage caused by the Scarlet Rot. Additionally, there is a Site of Grace here where you can rest and replenish your health if you have taken too much damage.
At the Site of Grace, you must travel south across the lake and find some pressure plates you need to stand on. Once these structures appear, you will need to go west until you reach a small building that contains a chest.
When you open the chest, you will find the Nomadic Warrior’s Cookbook . Obtaining it allows you to craft Rot Pots, Rot Grease, and Drawstring Rot Grease.
