The Breach league ran from December 2, 2016 to February 27, 2017.
Tears in the fabric of reality have formed throughout Wraeclast. Engage them to expose an alternate realm and reveal those who dwell there. Slay monsters inside the Breach to keep it open long enough to reap your bounty.
The Breach league and Hardcore Breach league were past challenge leagues. The leagues started on 2016-12-02 along with the release of version 2.5.0, and ended on 2017-02-27. There were 40 optional challenges, and players were rewarded with Breach-themed microtransactions after finishing 12, 24, and 36 challenges.
In this league, there were breaches that appeared in zones. Approaching a breach opened a parallel realm containing otherworldly monsters. The breach continued to expand as more breach monsters were killed until it eventually collapsed. Splinters dropped from enemies within the breach, which can be combined into a Breachstone to challenge the Breachlord in their realm.
All characters and stashes were moved to Standard league and Hardcore league respectively when the leagues end. Characters that died in the Hardcore Breach league were immediately moved to the permanent Standard league.
