Banefire effect for a weapon?

[Nerfix]

Is there something that could be used to create a banefire effect ala small area fire or perhaps the banefire burst of the banefire crossbow with the help of #secondaryeffect? I'd need it for the terrifying whip wielded by the even more terrifying Angel of Death.

Also, if I put more than one attack on a weapon, will the #secondaryeffect also trigger many times?
