"This ogre-mage is more diminutive than most you've seen. He has a shrewd look about him, and he seems to be regarding you with something resembling disgust. You'll have to talk to him to find out why."
Omaga is a merchant near the entrance to Coveya Kurg'annis.
Omaga is equipped with chainmail +3 and Shield of the Magi (light shield +6, arcane spell failure chance 0%, bonus level 4 slot for wizard/sorcerer/bard, can cast Lesser Globe of Invulnerability and Greater Magic Weapon at caster level 15, 1/day each). Alas, he lacks proficiency feats to use his equipment, so it will be unequipped on spawn, heavily reducing his AC while also removing his 30% arcane spell failure chance.
He also has unequipped greatsword +4 in his inventory - and lacks proficiency to wield it.
