Minecraft Dungeons:Mage

The Mage was a magical and illager mob that was planned for Minecraft Dungeons, specifically the Creeping Winter update. It was added into the files in the game's release (1.1.1.0), but was removed for no apparent reason in the 1.2.0.0 patch. It would have possibly been in the Iceologer's place but was removed before the DLC was released, probably because its purple color was already used by the Illusioner, or because it didn't match well with the winter theme of the DLC.

Trivia
The mage is very similar to the Iceologer but he is purple and has golden edges, instead of being blue and having white edges.
