A mystic robe top is magic armour worn in the body slot. It comes in blue, light, dark, and the special enchanted version Enchanted robes, but all offer the same bonuses. All mystic robe tops require 30 Magic and 30 Defence to wear. The blue mystic robe top can be bought from the Wizards' Guild in Yanille. The shoulders resemble those of a Cape of Accomplishment. The white mystic robe top can be bought from other players or found dropped by Kurasks, which require level 70 slayer to kill. The black mystic robe top can be bought from other players or dropped by Gargoyles which require level 75 slayer to kill. During the time they were released, WildyWyrms dropped the black mystic robe top as well.
Before 13 May 2010, the Mystic Robe top on a female had a large, somewhat suggestive, split up to about the middle of the chest. As a hidden update under the DirectX compatibility integration, the split was written over with a texture to hide the "skin." It is not known entirely whether the original graphics were intended, though a similar situation seemed to have happened with Verac's brassard.
Despite being dropped by few monsters, collecting a blue one from the Corporeal Beast will yield a message in your Adventurer's Log. It is unknown if this was intended or not due to its combat level.
