Original Sword Skill


 * This page is for the original sword abilities player-created in ALfheim Online. For the list of SAO's sword skills, see Sword Skills.

Original Sword Skill, abbreviated as OSS, is a system introduced in ALfheim Online which allows the player to create a sword skill of their own, the downside being that such skill is only accepted by the system depending on the speed, combo and final hit of the skill. To create an OSS the player must be able to execute the skill flawlessly, at the same speed as the completed skill and unassisted by the system. This should be impossible without the system but players have managed to create various OSS. "Skill Manuals" can be created to hand over OSS to other players, this caused players to sell Original Sword Skills and combos with 5 hits or more are especially expensive as they are very hard to create, however each player can only give one Skill Manual of each OSS, meaning that it can only be given to one other player.

Besides adding the ability to automatically use desired moves, it also adds the sword skill a magic effect, which can be from fire, earth, lightning, water, holy and dark. A skill can have up to two elements and the damage rate of the skill is a combined percentage between the physical damage and the magical damage.
