How to Obtain:

BRING TWO RECALL RINGS FOR THE KNIGHT DOING THE QUEST

  First, you must get the killing blow on the Quacksmith and behind him you will find Magnus (looks like a Yasnaki Thaum). Drop the Greatsword at his feet and say Magnus, teach. 
  Magnus will then take the Greatsword and drop a black pearl on the ground. Pick it up. 
  
  Second, return to Leng town, find Adjoran and ask him to teach.
  
  Third, You WILL need killing blow on Ser Lucius. (As of 10/2021 you do NOT need killing blow, simply being in a group and on the same screen will work.)
  In the far South East of Ser Lucius lair, you will find Torsten who also looks like a male Yasnaki Thaum. Drop the black pearl at his feet and say Torsten, teach. 
  He will then drop your shiny new and upgraded Greatsword.

Congratulations!
