Balefire Gun

Balefire Guns are flamers that uses highly refined promethium fuel mixed with a number of radioactive compounds to both burn and irradiate foes.^[1]

They are effective against Orks and other xenos with natural regeneration and are only rarely deployed due to the collateral damage it causes to the local environment. They are used solely by the Deathwatch to cleanse particularly resilient xenos and effective in controlling and eradicating Ork infestations.^[1]
