Like a ring of life and regardless of charge, a ferocious ring will be destroyed after saving the player. More than one ring can be owned at a time. There is no requirement to wear the ferocious ring, except that players must have Kuradal's permission to enter the dungeon; and they can only attack the monsters in the dungeon if they are their current Slayer assignment (assigned by Kuradal or Morvran), leaving an indirect requirement of level 110 combat and level 75 Slayer to obtain it. The ring can be recharged with a Slayer master, using co-op points.
