Durok's Bane is a heavy armor set. When you take damage, you apply Major Defile to the attacker for 4 seconds, reducing their healing received and Health Recovery by 30%. This effect can occur once every 8 seconds per enemy.
The Durok's Bane set is part of the base game. It drops in Selene's Web in Reaper's March. Each set item is bound on pickup. You can acquire heavy armor, weapons and jewelry of this set in the Ebonheart Pact, Aldmeri Dominion or Daggerfall Covenant motif style.
