The Magmaul is a Diamont weapon that fires superheated magma grenades. The magma grenades can be bounced off floors and walls to get extra range and strike at enemies hiding behind barriers. When charged, it can either launch a powerful explosive magma grenade (if used by Samus Aran) or a large fireball (when used by Spire), both of which can set enemies on fire. It is the favorite weapon of Spire, the last of the Diamonts.
