Maybe a dumb question, but the Desert attack power...what damage type is that? It's described as burning winds and cutting sand. Does immunity to fire protect a character?
that they would count as fire, due to the heat element; though, likely it would count as physical damage due to cutting wind/sand/heat combination. I would say that, at best, it is arguable—this damage stems from enough multiple sources that it would not be easily resisted, even by a GB of Fire (at my table).
If you're hoping for someone else to weigh in, you may wish to + them in the convo as well. Are you in the Ebon Dragon's Rostrum? We have discussions about what is what there from time to time.
+Mason Munden Ebon Dragons Rostrum? Is that a g+ group?
Unless explicitly billed as energy X, you can assume that attack powers always count as normal physical damage. It's up to the GM to decide what constitutes explicit billing, but I wouldn't include the Desert attack power among them.
