Diana first fight

Barong will respawn infinitely but don't worry, kill one and you will get a repel buff. Go to Diana and let her hit you once to reflect her own attack then kill another Barong, repeat until she's dead(or use Makarakarn). Leave and enter again, talk with Gryphon and go to Diana for a second fight without gimmick.

Kill each group of demons once until you get Efreets, then you can focus on killing Abraxas. The second fight will be normal.

You can teleport to this area and repeat the fights anytime.

If you defeat Black Maria before any Wil o'Wisp suicide or be killed, you get Black Maria plugin.
