Still, in pursuit of Ashtaroth, Mari and the Grand Chase enter the land of Archimedia when Mari suddenly loses consciousness among the Relics of Kounat. While unconscious, the Soul Stone makes contact with her and reveals all the secrets behind the destruction of the Kounat kingdom. The Soul Stone contains the ultimate essence of the divine and has hitherto remained buried within the ruins. Mari then absorbs the powers of the Soul Stone and is transformed into the Geas.
"Geas" once referred to someone who was exceptionally gifted into communicating with the divine in the ancient kingdom of Kounat, one who was a step closer to the deities than everyone else.
The Geas takes advantage of her enhanced speed and mobility and unlike her third job which fought primarily by installing machines and summoning magic, Mari takes advantage of combinations quick reactions and special skills operated by simple commands. Barrier and Canceler are added to her MP skills, allowing her to nullify enemy attacks. Long-range attacks are also possible while in Seize mode. Geas can summon magic orbs that prevent enemy MP from being restored while eliminating AP. Also, using the special technique Drain prohibits AP characters from using their specials and critical skills for a set period.

- Geas is known as La Geas or Magic Queen on the other servers.
- In Irish mythology, a geas is an obligation or prohibition magically imposed on a person.
- In Mari's Black Witch Awakening set, Geas receives a visual overhaul with new animations and a red color theme.
- According to a Brazilian article, Black Witch is Mari in an alternate reality where she is the reincarnation of Agnesia instead of Rin. In this timeline, Mari is easily manipulated because of her amnesia and follows the Twilight path.
- Interestingly, the rune that appears above her when performing Freeze Tempest has the same symbol as the ones that Ley uses for her Specials.
- Oddly enough, Mari appears as Geas in Ra Canyon despite the events of Alcubra occurring long before she becomes one in Archimedia.
- Rune Caster's Core Break shares the same name with Geas' fourth-grade Special attack.
- Geas had been stated to be the last MP class to ever be released. With Rin's arrival, however, this claim is no longer standing.
- Upon advancing to Geas, Mari gains a triangle-shaped jewel on her forehead.
- In the game, however, it only appears when equipped with Soul Taker.
