Flamespewer Feat 13

You like to tinker with your weapons so that they can spit fire. During your daily preparations, you can tinker with one tech weapon, using an upgrade slot to apply a chem tank to the weapon until your next daily preparations. The weapon deals fire damage and gains the boost 1d6 and critical (flame) traits. If it already dealt fire damage, it gains the boost 1d8 trait instead. Each time you boost the weapon, it expends 1 chem.
