Weapon LoadoutsEdit


  • Until Update 13.0, the Amphis was not used by any Grineer unit. This would be a little over 1 year between the Amphis's introduction (February 22, 2013) and Guardsmen being added into the game (April 10, 2014).
  • On Jump attacks, the Amphis releases six small streams of electricity that each travel outwards lead by a sparking orb. This cosmetic effect is shared with the Prova8point2 Prova.
