The Geomancer is an illager mage, which is noted by its thick beard and eyebrows. It wears dark brown, ragged clothing and a purple crystal necklace around its neck. It is often seen with a walking stick and it uses this to summon walls of stone. Unlike other illagers, the Geomancer bears purple eyes instead of the normal blue or green eyes. It's skin also appears to slightly have a caveman aspect. gamepedia
