In most Dragonlance books (Chronoicles+Legends), dragon breath attacks are classified per color/metal. Alhough confusing, especially with metallic dragons and their dual weapon, it makes sense.
However, in The Legend Of Huma (by Richard Knaak), the silver dragon
appears to be able to breathe fire. Moreover, she says that any dragon can breathe fire, but it is very taxing on stamina.
Do silver dragons breathe fire? Or is it an inconsistency with the TSR canon?
