The Corrupted Priest is a side quest in Egypt (Act II). It is given by Amen-nahte, a young priest found in the Temple of Seti. He will tell you that when the Telkine came through, the temple's head priest Neb-Kemi stood against it, but the Telkine turned his spells against him and Neb-Kemi became 'transformed'. You are to search for the priest in the deserts. After you have killed Neb-Kemi, return to Amen-nahte in the Temple of Seti to complete the quest. You will get experience and a random magical weapon, usually of rare (green) or epic (blue) quality. Reward: 15 000 EXP and a Magical Weapon
