Under Improvised Weapons:Often, an improvised weapon is similar to an actual weapon and can be treated as such. For example, a table leg is akin to a club. At the DM's option, a character proficient with a weapon can use a similar object as if it were that weapon and use his or her proficiency bonus.
Because the fiery blade is similar to a scimitar, it can be treated as a scimitar which does 1d6 damage.ncG1vNJzZmivp6x7prrWqKmlnF6kv6h706GpnpmUqHykrc1msKitXZiutMCMn6OapZVir62tw55kmqaUYsGpsc1mpJqjlWKur3nIpqerp6aewKawjLCcmqifo3qiwNOamqRlp57BqXnToZxmnpyWuqZ5waWYnZ1ebH1yfo9yZqmZl5p6cnw%3D
