- Effective against all unit types. - Commander Unit. - Commander with XV8 Crisis Battlesuit, Plasma Rifle, Flamer, Shield Generator, Vectored Retro-thrusters, two Gun Drones, Puretide Engram Neurochip. - The first Tau to be fitted with a Puretide neurochip, Sha'vastos was saved from his subsequent lobotomisation by the intervention of Commander Farsight. His prototype neurochip suffered rapid degeneration after the battle, however, so Farsight had him secreted away in stasis until he could find a cure. Many decades later, O'Vesa was able to recalibrate the neurochip and reawaken the old warrior. - Can jetpack quickly around, and over, the battlefield on longer distance than ordinary Crisis Battlesuits thanks to Vectored Retro-thrusters.
