The Mastema Skell

Mastema is a Heavy Type based Skell unit in Xenoblade Chronicles X. Mastema is one of the Skells manufactured by BLADE in New Los Angeles. The Mastema's vehicular form is a sort of futuristic multi-legged and seemingly-amphibious vehicle.

The level 60 upgrade of this Skell is the Mastema White Reaper.


Mastema is a Heavy Frame based Skell model. It is excellent in distance combat because it is specially designed for Ranged Attacks. However, due to a very high weight it is difficult to maneuver. Its vehicle mode is multi-legged, bearing resemblance to a spider.
