This ancient sword was forged out of Outworld steel by Shao Kahn and it possesses the same strength as the Emperor, thus it was used to slaughter many enemies and traitors alike in kombat, and in interrogation as well. The sword serves as the reminder of Shao Kahn's dominance and merciless nature.
The Sword of Shao Kahn was also endowed with the magic of the Emperor's loyal Shadow Priests, making it stronger. This pleases Shao Kahn greatly.
Shao Kahn unsheathes his own beloved blade once again in kombat against the Earthrealm's thunder god Raiden after he revealed the truth to the people of Shakaana and ordered them to abandon their city forever.
