Blood Raven is located at the center of the grounds and usually surrounded by Hungry Dead. She can be a nasty foe to defeat for lower level characters due to her higher-than-usual level, her ability to shoot fire arrows (along with an additional random bonus mod), and the ability to resurrect more of her "army of the dead" to assist her. It is best to defeat her at level 8 or higher. When defeated, her corpse momentarily floats in mid air while streams of lightning shoot all over killing off the remaining undead.
Two sublevels are located in the Burial Grounds: [[The Crypt]] and
the [[Mausoleum]]. Neither are linked to completing a quest but are decent areas for the chance to level up and find additional and possibly useful items.
The Mausoleum in hell difficulty is alvl 85 making it a popular area to clear out for the chance to find high-level items.
