A light mystic robe top is mid-level magic armour that requires 50 Defence and completion of Dragon Slayer to wear. It is part of the light mystic robes set and comes in two other colours: blue and dark. It cannot be crafted from mystic cloth unlike the standard blue variant, and is only available as a drop from Kurasks.
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.
