I thought only Fiery Dragon Swords could have a fire hilt? Today I found some other sword with a fire hilt... I expert salvaged it though and got the other crappy enhancement of +4 Armor...
Fiery refers to the fact that the weapon deals fire elemental dmg. It is just incidental that all dragon swords in GW (so far that is) are FIERY elemental. It's like saying all Dogs are 4-legged animals so all 4 legged animals must be dogs. This isn't true. All Dragon swords are fiery but there are some fiery non-dragon swords too.
