My party recently ran into a Bodak. One of it's nastiest features is it's Death Gaze (Su) gaze attack which causes:
1d4 negative levels, 30 feet; Fortitude DC 18 negates. The save DC is Charisma-based. A humanoid slain by a bodak’s death gaze rises as a bodak 24 hours later. This is a death effect.
Are the negative levels bestowed by this attack temporary (as per the Energy Drain universal monster rules) or are they automatically permanent?
