Sword Skills


 * This article is about the original Sword Skills that are available in Sword Art Online and are later introduced to New ALfheim Online and Underworld. For a list of Original Sword Skills that are introduced in New ALO, see Original Sword Skills.



«Sword Skills» (ソードスキル) are «Sword Art Online's» combat movements that are assisted by the system. Most Sword Skills are named in English, the only exception being Katana and certain Martial Arts category skills, which are named in Japanese, but written in the English alphabet.

Sword Skills are later introduced to «New ALfheim Online» with minor modifications, including elemental attributes, and allowing the players to create their own skills, though it is rumored that about ten skills were removed during the adaptation, however, whether this is true or not has yet to be confirmed. Sword Skills are also present in Underworld.

Mechanics
Sword Skills are activated when a player performs the appropriate «Pre-Motion» (予備動作)  for a skill (such as raising a sword atop one's shoulder). As soon as the system recognises the motion, the player's weapon begins to glow in a colour specific to a Sword Skill. The player can then allow the system to take over and automatically complete the skill at a speed that is normally near impossible for a player to achieve and dealing much more damage than a regular sword swing.

After a skill is completed, the user is temporarily rendered rigid in a state called a «Post-Motion» (技後硬直), during which the user is made vulnerable to any counter-attacks. The higher the level of the Sword Skill used, the longer the «Post-Motion» period is.

After a Sword Skill has been used, the skill enters a «Cooling» (冷却) period, which is displayed as a cooling icon at the bottom of the player's view. Until this period ends, the same Sword Skill cannot be used, however, any other learned skills that are not in a cooling period can still be used.

The amount of available Sword Skills and their type depends on the Weapon Skills that the player has trained.

List of known Sword Skills in Underworld
Generally, all Sword Skills available in Underworld (called «Secret Art Finishing Moves» or just «secret moves» in this world) are exactly the same ones that existed in Sword Art Online, but the residents of Underworld have given each of them a new name. Although, unlike in SAO, the «Sword Skills» that can be used by a person are determined by the «Priority» class of the weapon used, the higher the Priority, the higher combo skills can be used. Currently, only up to 4-hit combo skills have been used. Also, when a Sword Skill encounters another Sword Skill in Underworld, the two skills will not reflect each other occasionally, due to user's will, unlike in the original system in SAO.

Additionally, several Sword schools have been created in Underworld, each focusing on specific Secret Arts to ensure that both swordsmen in battle would know what skills each of them could use to prevent accidentally dropping the «Life» of one's opponent.

Aincrad-style
A style "invented" by Kirito due to his knowledge of various Sword Skills in SAO.

Note: All moves of this class are named after the «Sword Skills» in SAO and all skills available in SAO are also part of this style, but only skills up to 4-hit combos can be used right now.

Zakkalight-style

 * «Azure Wind Slash» (SAO «Slant»)

Serlut-style
A style created by the Serlut family after they were forbidden from inheriting the High level Norlangarth style.
