Spell Breaker

Spell Breaker, superficially a Dwemer tower shield, is one of the most ancient relics of Tamriel. Aside from its historical importance in the Battle of Rourken-Shalidor, the Spell Breaker protects its wielder almost completely from any spell caster, either by reflecting magicks or silencing any mage about to cast a spell. It is said that Spell Breaker still searches for its original owner, and will not remain the property of anyone else for long. For most, possessing Spell Breaker for any length of time is power enough. —Yagrum Bagarn, Tamrielic Lore

Found in the Dwemer ruin Bthuand, which is near the northern coast of the mainland just west of the Daedric ruin Zergonipal. The shield is hidden among some rocks in the south-southeast part of the ruins near a dead adventurer. This shield is needed for the vampiric quest from Mastrius, in Salvel Ancestral Tomb.
