Summon Undead (SU)
Summon Undead (Sp):
Once per day, a 5th-level thrall of Orcus can summon 1d4 ghouls, 1d3 shadows, 1 wight, or 1 wraith as the summon monster spell cast by a caster of her class level. At 9th level, the thrall can summon 1d3 mummies, 1 spectre, 1 mohrg, 1 vampire, or 1 ghost instead. If she chooses a vampire or a ghost, its ECL (not counting the vampire or ghost template's LA) is one less than the thrall's class level.
