The SDFMG (or Space Duke Fishron Machine Gun) is a craftable post-Moon Lord gun and an upgrade to the S.D.M.G. It rapidly fires bullets with a 20% chance to instead fire a water rocket that homes in on enemies.
Its best modifier is Unreal. But the weapon's firing speed will not be affected.
- Its insanely fast rate of fire gives it incredible synergy with the Reaper Tooth Necklace.
