Has anyone recently tested what exactly this applies to? Near the end of beta, one tester found that it only applied to fire-based class skills and nothing else, not even destruction staff skills. However, the Dunmer passives were tinkered with a bit after that for release, but I haven't heard of anyone testing it since.

I'm specifically interested in weapon enchants and the Ashen Grip set, which procs "flame damage," although it would be nice to know if it affects destruction staff basic attacks and abilities as well. I'd test all this stuff myself but I can't afford the skillpoint refund at the moment to do so.
