A forum member named Darth Vigorous made a sound font called "flaming torch". That's what I used to do my flaming sword and flaming whip sound fonts. It doesn't have sword sounds though, just fire! The steel sword font and the torch font can easily be mixed together though!
Thanks, I think I would like it purely fire though, it fits for a sword that is pure flame/plasma. I will see if I can find that font and repost it here.
