Stormbringer is a chaotic artifact, and the only runesword in the game. It is considered a broadsword for skill purposes. It drains life from monsters it attacks. It is bloodthirsty, attacking peaceful monsters and pets without confirmation if you walk towards them.

The damage and to-hit bonuses are applied only against creatures not resistant to level drain.

Encyclopedia description

                  There were sounds in the distance, incongruent with the
                  sounds of even this nameless, timeless sea: thin sounds,
                  agonized and terrible, for all that they remained remote -
                  yet the ship followed them, as if drawn by them; they grew
                  louder - pain and despair were there, but terror was
                  predominant.
                  Elric had heard such sounds echoing from his cousin Yyrkoon's
                  sardonically named 'Pleasure Chambers' in the days before he
                  had fled the responsibilities of ruling all that remained of
                  the old Melnibonean Empire.  These were the voices of men
                  whose very souls were under siege; men to whom death meant
                  not mere extinction, but a continuation of existence, forever
                  in thrall to some cruel and supernatural master.  He had
                  heard men cry so when his salvation and his nemesis, his
                  great black battle-blade Stormbringer, drank their souls.
