I believe that adding a method to crafting food or potion by cooking can also be an interactive method for players to collect certain items and other materials to craft food or potion that may have a slight boost advantage compare to the ones that can be buyable in the market/shop around the World.
Cooking can have a value in trading as players who are too busy grinding or doing other activities would be persuaded to buy items that is crafted/made by the cooking method. This could also add value to the Market for players who wishes to make profit from cooking items instead of the usual equipment drops from mobs, or bosses within the game.
Items made from the Cooking system could have a boost in certain aspects of the user’s stats for a limited time. This could be profitable and valuable to players who loves to raid or go explore often then interacting with other players in the vast world of Vesteria.
Note: This is just a suggestion I had that could add value to the gameplay for people who has interest in increasing other aspects of their skill chart or stat if they aren’t into the type of just focusing on increasing the mainstream skill sets such as Intelligence, Strength, Vitality and etc.
