Walkthrough
Level 1: Upon entering turn right and move slowly to the pit filled with water and littered with coffins. There will be pop ups. Turn east from the pit and you will find the first inscribed creature (lvl 28). Return the way you came to the starting point and then proceed to the left to reach the second dungeon level.

Level 2: On this level there are pop ups and some Incubi that bob up and down from the ceiling. Continue south-east through the large group of Skeletal Hounds where you will find the second inscribed creature to kill and the portal to the next level. The room will be filled with skeletons of various types, some of which will activate when you attack the inscribed creature. All skeletons will disappear on the creature's death, so it is useful to focus-fire (the hounds will not disappear if not dead).

Level 3: The route through this last level is straight forward, just watch for the pop ups. You must defeat the Inscribed Guardian in order to complete the mission. He is surrounded by Enchanted Shields that will block melee characters from attacking. Once the guardian takes damage, the enchanted scythes nearby become active and start attacking you. Kill the guardian quickly and the mission will end.
