https://minecraft.wiki/w/Minecraft_Dungeons:Illusioner

Illusioners are illagers that look very different from illusioners within the original game. Instead of a blue cloak, illusioner wears a dark purple cloak, dark boots, and a hood with dark outlines on the edges. Under the cloak is leather clothing, with a leather bag, belt, and iron buckle. Illusioners also have pink eyes, which are brighter than the eyes of other illagers.
