This is a work in progress, as such information may be incorrect or incomplete. * see also Cook (NPC) The Cooking skill requires no manuals, as long as you have the materials and the proper skill level, cooking is easy as 1-2-3! Cooking formula: the purchase price of finished product x 2 = minimum success number. For example, with Meat, you need to make the minimum success number = 70 x 2 = 140; if a Chicken Feather is the material, then you will have to make the minimum success number = 140/19 = 8 (can be more essential)
