Kill Spiritchaser Parunru. - Up the first stairs, with the rocks on either side, you can go left and jump, very carefully, up to bypass the Nunu at the top. Cross the courtyard to the single stairs and kill the two Scratchers (not as hard as they look) and go up the stairs to the Spiritchaser. Spiritchaser Parunru is a Level 38 4-dot Soloable, at the Altar of the Black Dragon. He has a spell that will freeze you for 10 seconds or so, during which time he will beat you like a red-headed stepchild. Have a heal ready the moment you can move as he will follow it with a big Direct Damage spell.
