Ahem. Light has mass, as it is composed of photons. The gravitational warping of light by black holes is an example of how their mass is affected by a physical force.

As for everything else, that seems fine. I assume the life drain applies to the Field Emitter and Black Flame as well, meaning that those two don't deal physical or heat damage as well?

Photons don't have mass though? They just have momentum, which from a wikipedia refresher seems to be the reason for physical interaction.
