[Ygorl]

In the Council of Wyrms game, I had a Tartarian with Air 2 and Nature 5. I loaded the beast up with penetration items (note that increased nature magic increases penetration for nature spells), wind rode to provinces in which enemy SCs lived, and charmed their pants off. I captured several nice former enemies like this. A crone is a lot easier to kill than a Tartarian, of course, so this is quite a bit riskier. As long as you're careful with her, though, she could be an extremely effective charmer.
