(5e) Are there any magic items that allow a user to bypass fire resistance with a magical weapon?

A bit of a specific request I know, but for an upcoming battle my DM is throwing at us, I’ll be using a magical weapon that deals fire damage and we know the creature has fire resistance. So I was wondering if there were any options to ignore the opponent’s fire resistance. I know of the Elemental Bane spell already, but if there were any other spells that had this effect as well that would be helpful to know as well.
