To get Alchemy, you must have certain types of armor. For your helmet, you must get HUNTER'S HELMET. For your plate, you must get BATTLE MAIL. For your Gaunlets, you must get CHAIN VAMBRACES. For your Tasset, you must get VELOCIPREY TASSET. Your Leggings can be anything. Remember to register this as one of your equipment sets. I don't know how to get the burnt meat into raw meat (sorry).
