In the International Zodiac Job System version, Vanishga is listed as a Time Magick 8 license costing 90 LP. Vanishga's MP cost is reduced to 24, and it is available for 3,800 gil at the Mosphoran Highwaste. Vanishga is available for the Time Mage and Machinist job classes; although Machinist must obtain the license for Famfrit first.
Vanishga appears in Final Fantasy XII: Revenant Wings as an ability learned by Llyud at level 25. The ability renders all selected allies within an area-of-effect invisible.
