Illusioner is one of the unreleased Illagers in Minecraft. It's a pity because they have plenty of interesting abilities and potential. Given the vast diversity of Illager forces in Minecraft Dungeons, I'm quite surprised that there aren't more illagers. This lady has blue hair of a different shade from her robes. In my mind, she is a powerful sorceress. You can use the skin for anything from texture packs to actual skins. All I ask is that you don't claim you've made it. :)
