Blowtorch

This spell creates a small blue flame at your fingertip, this flame can deal 2d8 fire damage if your close enough, and attack rolls with this flame have advantage with a additional +2 to hit. 

This spells intended use is to weld two pieces of metal together with tacks. It takes 6 seconds to create a single tack, once a tack is created it requires a strength check to break. This strength check has a dc equal to the number of tacks you create on that piece of metal. Once welded the metal can only be broken.
