ALfheim Online

«ALfheim Online» (アルヴヘイム・オンライン) is the successor to «Sword Art Online». It can be played with any version of FullDive technology. The game features multiple races of fairies, whose goals are to reach the top of the giant tree Ygddrasil in order to meet the Fairy King Oberon. Oberon will grant the chosen race the ability to fly indefinitely once this goal is achieved.

It is the setting for volumes 3-4 Fairy Dance. Instead of the level system that SAO emphasized ALO pursues skill development and encourages killing other players.

System
ALO is made from the same system as SAO. The entire game is monitored and maintained by a system called «Cardinal» which self corrects any problems and creates its own quests. Unlike SAO it also uses magic and disregards the leveling system, making it completely dependent on skill.

ALO attack formula is not complicated. It depends on four things: Power of the weapon itself, where on the opponent's body the attack hits; attack speed; and the armor worn by the opponent.
