Priestess Delrissa is the third boss in the Magisters' Terrace instance. She comes with four NPCs, randomly chosen, similar to Hex Lord Malacrass in Zul'Aman and Moroes in Karazhan. All 5 of them must be defeated to beat the encounter. The style of fight is similar to an arena 5v5 match, and somewhat like the alternate Ring of the Law encounter in the Blackrock Depths.
