Sword Skills

«Sword Skills» are «Sword Art Online's» combat movements assisted by the system, activated when a player performs the appropriate initial movement (such as raising a sword above one's head) and then allowing the program to take over and automatically complete the movement and combo. The player's weapon typically glows in a color specific to a Sword Skill when the skill is activated. Sword Skills are later introduced to 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.

These skills fall into four properties: Thrust, Slash, Pierce, and Blunt. There is also another beginner ability: Final Thrust. 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 Arts, finishing moves or secret moves in this world) are the exact 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 Object Control Authority of the weapon used, the higher the authority, the higher combo skills can be used. Currently, only up to 4-hit combo skills have been used.

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