Grand Master

Grand Master is available as a reward for reaching 75 stars in the Overthrow campaign. He can also be obtained by trading in 75 Sacred Codes of Imper. These in turn can be obtained by trading in Goliath Slayer (Captured Destroyer) or Armour Breaker (Menno Doomerville tank) convoy marks at the quartermaster, at the rate of 2 marks for 1 code, or at the Catacombs shop at the price of 36 diary pages for 5 codes.
