The Spirit Realm

Anyone figure out what cures Crystalline Expuntis, off mobs in Warrens? Its chromatic, and I tried RGC, Disinfecting Aura, and RC multiple times. Any help is appreciated.

Radiant Cure is hit or miss, but that's the only one of the spells you listed that has a chance to work. You could try to use Pure Spirit a few times, but just good old fashioned dispel spells are an option as well.

Radiant Cure, insta AA Cure alls(paladin, monk and cleric have) or the shaman spell Pure Spirit can cure it.

For a paladin, you could also use a combo of an empty buff slot up top, several junk clicky buffs, and Nullify Magic. That's how players had to deal with Malo & such (Crystalline Expuntis being "such") up until Luclin.
