The rules for breath/blast/bolt state that they do FULL damage to all targets in the area. I have originally understood this to mean that it does all damage rolled by dice, unmitigated by any armor source. However, after rereading it many times and realizing just how powerful this makes hellhounds, I have reconsidered the meaning of this "full damage". I am thinking it may actually just be there to meant he damage doesn't disipate over its larger area of affect, rather than meaning it's unmitigatable.
So which is it?
Does breath/bolt/blast deal FULL damage to all creatures?
Or does breath/bolt/blast get mitigated by armor?
