To record a new OSS, the player needs to open the menu, move to the OSS panel and activate the Sword Skill recording mode by pressing "Start" there. After that, the player only needs to swing one's weapon in a desired set of moves and press "Finish" once done. The downside of this system is that such skills are only accepted by the system if they meet very high speed, combo and execution requirements. To create an OSS the player must be able to execute the skill flawlessly, at the same speed as the completed skill but unassisted by the system. This should be impossible without the system's assist, but players have managed to create various OSSs.
