I cant think of any situation those two spells are of any other use then to show off. For me they do around 350-500 damage which seems to be little underwhelming for 5 minutes cooldown and forever cast time + they put Heros Resolve on cooldown. Someone suggested to use it with Primal Cast but literally any breath attack will do better. On other hand none of my dragons is very good with spells. So I wanted to ask how others use them?
