Food is an edible item in Age of Aincrad. It's perpared by players who have the cooking skill. Food has many different effects, such as increasing your max hp for a limited time, or it buffs your strenght for a bit.
Preperations
To prepare food, a player needs to find a recipe which allows him/her to make it as soon as he/she gathers the ingredients needed for it. Then he/she goes and prepares it in a place suited for cooking.
Food recipes can be found in chests, recieved by trading, dropped from monsters, looted from other players dead bodies, stolen from them, bought on the market, received as a quest reward from NPC's, or even dropped by bosses. Usually the most rare kind of recipes drop only from bosses and are very expensive.
