Flaming Weapons: Magical attack?

[Epaminondas]

Does the Flaming Weapons effect from Fire Bless count as a magical attack--i.e., does it confer you the ability to hit ethereal units? Also, what about Weapons of Sharpness?

Or are there any other Bless effects or buffs that confer regular rank-and-file magical attack effects? (I know some units wield magical weapons, so that's not what I am looking for.)

Thanks.
