After completing 3rd class Quest, all classes on ParagonMu can start their Mastery Armor Progression.
All Set parts can be bought from Ruud vendor in either Lorencia or Elbeland.
(there is a separate guide on how to get Ruud)
Each class has their own specific set. And on Paragon Mu set options are adjusted to maintain PvP Balance.
Some classes such as Elves, Knights, Magic Gladiators have 2 sets to chose from.
Knights can chose between offensive and defensive set.
Elves can chose between agility or energy set.
Gladiators can chose between energy or strength set.
Each set can be upgraded, increasing its offensive and defensive stats.
On ParagonMu we have lowered the level requirements. You must reach the required level in order to be able to wear the item, however once you equip it, it will work from level 1.
