Diablo 1 Walkthrough -> Na-Krul
The only task in the Crypt is to kill Na-Krul. You’ll learn about it from the books you’ll find throughout these levels. But before his death, the scientist trapped this creature. To release it, you must read three books in the correct order. You’ll learn this from the Reconstructed Note, which you’ll piece together from three Torn Notes.
You’ll find Na-Krul’s room on the fourth level of the Crypt. Near the entrance, there will be three bookcases and a lever next to them. If you read the books out of order or pull the lever without reading them, Na-Krul will emerge and be very, very difficult to kill.
So, the books should be read in this order: middle, left, and right (In Spiritu Sanctum, Praedictum Otium, Efficio Obitus Ut Inimicus). Upon his death, Na-Krul will leave behind the following magical items: Great Sword, War Staff, Long Battle Bow or Long War Bow.
