Seal Breaker Key Shadowlands: How to Get Nilganihmaht's Silver Ring

Similar to Runebound Coffers in Maldraxxus, Seal Breaker Keys are a means to open a chest in a new type of way.

In The Maw's Beastwarrens, located within the Desmotaeron, are Domination Sealed Chests, contained in thrice-locked cages.

Seal Breaker Keys can be found one or two at a time inside Helgarde Supply Caches, scattered about Desmotaeron. Simply farming Maldraxxi Defectors can yield a key here and there. A rare by the name of Ylva also drops one in the form of Feeder's Hand and Key, consume this item in your inventory and you will be granted a Seal Breaker Key.

Once you have yourself four Seal Breaker Keys, head over to a Domination Sealed Cage, and begin using your keys. It will take three keys to unlock the cage, and a fourth key to unlock the chest itself.

Opening the Domination Sealed Cage grants you Nilganihmaht's Silver Ring, one of the five pieces required to craft Nilganihmaht's Control Ring.
