Encounter Conversion: B13 Erylium the Quasit

The "Boss" monster of the Catacombs of Wrath in Burnt Offerings is Erylium. In the published adventure she is a quasit with levels added. One of the key elements of the encounter was her ability to fly. A 2nd edition AD&D quasit does not fly so I changed her to an Imp, increased her toughness based on the mechanics given for doing so in the DM Options: High Level Campaigns (-3 to +3 to AC, hit points per hit dice, Thaco, damage and saving throws), and added a few more special abilities based on Erylium's relationship with the Demon Goddess Lamashtu.
