On Durkon's domains, remember that he can also cast Thor's Lightning. We've never been able to pin down just what spell that is, and hence what published domains could account for it, but it's definitely not granted by Good or Healing.

Thor's Might (presumably a re-named Righteous Might) might also be a domain spell, but we can't be sure on that because it's also a standard cleric spell. But I don't think the standard cleric list contains anything, from any source, that could be Thor's Lightning.
