Skill (XCX)

Skills are a mechanic in Xenoblade Chronicles X that provide passive battle effects. Each playable character can equip Skills up to their number of Skill Slots. While most characters have a fixed number, Cross's number of Skill Slots is determined by the currently selected. New Skills are unlocked by increasing the character's Class Rank. Skills can be leveled up four times to Lv. 5 (labeled as Lv. MAX in-game), this requires Battle Points.

Cross can learn any skill in the game. Each skill can only be unlocked in a specific class. Other playable characters can only unlock up to eight skills.
