An Akali build guide is a suggested order of buying items and allocating skill points for the assassin character Akali. Oftentimes these guides are written by experts and go into great detail to improve one's gameplay.
Though anyone can make a guide, very skilled players will identify themselves by what tier they are in. These guides often list the recommended masteries to take for a champion as well as what runes to purchase. They can also give insight as to what lane is best for what champion and give a detailed breakdown against lane opponents that may prove difficult to face.
