Fashioned with Grineer materials and balanced for marine infantry use, the Amphis is a traditional staff weapon that has received a monstrous makeover that enables shock damage on jump attacks. Connects with multiple enemies with each strike.

The Amphis causes a stun effect with high Impact b Impact damage, making it very effective against Corpus shields. This weapon can be sold for Credits64 5,000. It is the choice weapon of Grineer Guardsmen and Prosecutors.

This weapon is a requisite ingredient for the Sydon.

Weapon LoadoutsEdit


  • The blueprint for this weapon was added on March 1, 2013.
  • The electrical AoE jump attack is especially effective against Corpus, paralyzing Crewmen and MOAs and reaching Ospreys.
  • Lethal blows send enemies flying like the Bo
  • Needed to build the Sydon
  • If equipped with Primed Reach the AoE jump attack blows up Bombard rockets. 


  • 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 Prova.

    • I've noticed it only knocks back enemies when it kills them, on Ancients for example it doesn't seem to stun or knock back.
