The Shem Drowne sword is a unique revolutionary sword found in Fallout 4.


Targets take radiation damage, although less than a simple legendary sword with an Irradiated effect. However, the effect applies radiation damage from two sources - pure radiation damage of 5, as well as a three second radiation damage over time effect, behaving akin to a poison.

  • Unlike its common counterpart, the Shem Drowne sword does not have access to the serrated blade modification at weapon workbenches.
  • The Pip-Boy interface sums up both the direct and the over time damage, leaving no hint that part of the damage is dealt over time.
  • Radiation damage bonus from perks is only applied to direct radiation damage.
  • The Shem Drowne sword has a unique legendary effect texture and is the only other weapon aside from the 2076 World Series baseball bat and the Rockville Slugger to do so.
