Magic Domain turn undead applies to Astrologians

[Diabl0658]

Defense of the Arcane: Nearby allies in a colossal radius who are bards, characters with the feat Courteous Magocracy, clerics with the Magic and/or Spells domain, sorcerers, or wizards, have a 50% chance to receive each of the following spells: Endure Elements, Ghostly Visage, and Mage Armor.

So, I quest with a magic domain cleric and an astrologian, and i've noticed this doesn't seem to apply to the astrologian in our party and always felt it was a bit weird. As a full arcane class, I feel it would make sense if it applied to them as well.
