Master Manuscripts are key items used to upgrade Master Skills: after a Master reaches Lv. 10, when Skill XP is maxed, you must consume Master Manuscripts to unlock and learn the next stage of the corresponding skill.

They can be obtained from rewards for leveling up Master Skills, random drops from Journey events, Pass rewards, in-game pack purchases, and exchanges in the Championship Shop. Please refer to the in-game info for other acquisition methods.
