From now on, Dragon Equipment can be upgraded with Marks. This is done the same way as adding Marks to Character Equipment is.

"Green" quality Dragon Equipment is fit with a single Six Schools of Adan slot while "blue" Armor has two slots - Six Schools of Adan and Master of Steel. Types of Marks available for use will depend on the Class of Dragon Equipment. All Marks that fit Six Schools of Adan and Master of Steel slots of Character Equipments also fit Dragon Equipment.

Marks can be acquired in a number of ways: as trophies during game Events; Marks of "violet" quality can be purchased upon reaching 7000 or 16000 Bonecrusher, Hero of the Empire or Conqueror of Seven Bridges Reputation; or created with the use of the Inscriptor Profession.
