Probably because Eldritch Blast isn't an energy attack. It does not have an energy type (so no creature can reduce its damage based on their DR unless it's DR/-).One I didn't see mentioned that is just killer for Warlocks is Mortalbane from the Book of Vile Darkness. +2d6 on all energy based attacks against living non-Outsiders? Yes, please!
