Blue mystic robes can be created from mystic cloth, along with 51-58 Crafting. Both dark and light mystic robe pieces can be found from various Slayer monsters. The dark set is mostly found on monsters that can be found in Slayer Tower north-west of Canifis, while the light set is mostly dropped by monsters in the Fremennik Slayer Dungeon. The top has the additional requirement of completing Dragon Slayer before it can be worn. Each complete set can be stored in a Magic wardrobe in a player-owned house. The robes are currently the best non-degrading magic armour for free-to-play.
