Evil Mage Lord
From UO Lost Lands Wiki
Evil mage lords can cast up to 7th circle spells and deal a lot of damage, however they will also die very quickly as they are unarmored. They are the only type of monster in the game which will say their "mantra" when casting spells (for example "Corp Por").
Evil Mage Lords carry 4 different types of hued robes, which can be cut into cloth to creating clothing out of this dark hue.
They drop level 3 treasure maps and around 250gp on death.
