Broken Rift Stabilizer
From Guild Wars 2 Wiki
Whatever this device did, it's clearly not going to do it anymore.
— In-game description
- Jumping into a Class I Magic Rift at least once with each of the 13 settings of the Class I Rift Stabilizer.
- If the Broken Rift Stabilizer is destroyed, you can obtain a new one by obtaining the Mysterious Device again, and turning it into a Class I Rift Stabilizer by talking to Auris Weirdbringer. However, you only have to jump through a portal once (instead of 13 times) in order to obtain the Broken Rift Stabilizer.
