Notes[] When the buff times out, one stack is lost and the buff duration resets. Headshot bonus stacks additively with  Target Acquired, innate headshot damage bonuses on weapons such as  Kuva Chakkhurr, and snipers with bonus headshot damage from scope bonuses.  Cernos Prime's headshot bonus is unique and stacks multiplicatively with Primary Deadhead's headshot bonus. Kills from some status procs on the target's head do not count as a headshot kill.  Electricity and  Gas procs are able to trigger the effect when aimed at the head however, as they are able to land headshots themselves. 'Precision' refers to direct hit headshots (not AoE). Tips[] Can be used on weapons which normally have a 1.0x multiplier to headshots (such as the  Arca Plasmor/ Tenet Arca Plasmor and Update 32 launchers such as the  Kuva Zarr and  Afentis) to give them a 1.3x headshot multiplier and actually provide a benefit. Since Electricity and Gas procs are able to independently land headshots, they benefit twice from the headshot multiplier bonus. Both of these procs will have 1.69x headshot damage from the bonus.
