Elor is hardly what I would call an over powered NPC. High level, yes. But his skills, spells, stats, abilities and the like are all very reasonable. In fact, for a 45th level NPC, he is a little weak on they physical side. But then, he sorta should be. He is a MYSTIC, not a brutish fighter. For spying and info gathering mixed with very reasonable offensive spell ability, a Mystic is great, but no knock down the wall Mage or Sorcerer.
Elor has some real personality. A bit of a caraciture perhaps, but much more fun than another ALL POWERFUL NPC that leaves the players wondering why doesnt this guy just take care of the problem(s)?
