Outside System Skill

An Outside System Skill (システム外スキル) is an ability, usually referred to as a skill, that either involves unconventional use of system-controlled skills, the exploitation of loopholes in the system or the use of the player's human abilities to enhance their gameplay. Although such abilities are referred to as "skills", none of these skills are regulated by the system, though some involve making use of system skills in ways that were not intended by the developers of the game.

These skills are developed through a player's capability in game and are acquired through experience and practice put in by the player themselves throughout playing time.
