Ghostly Archmage

In Warcraft III:The Frozen Throne, ghostly Archmagi are the souls of the dead Archmagi who died while preventing the invasion of Arthas in Dalaran. They have the same spells like of a regular Archmage but appear as its luminescent counterpart. In the Blood Elf campaign, they appear in Chapter 3 where Kael and Lady Vashj encountered several of them. Defeating them grants an item called the Archmagi Ring that grants a mana regeneration aura or the Brilliance Aura. In order to get the item, the player must first gather all the pieces of the ring by defeating all the ghostly archmagi, who drop the pieces.
