Challenge rifts are weekly challenges in Diablo 3 where participants are given a set character with set gear and must complete a rift in the fastest time possible. Challenge rifts unlock when you complete a greater rift solo.

• Submit your best solo time in this week's challenge rift in the America's Region (Challenge #372).
• Entries will be scored on the fastest competition time with (unlikely) ties broken by first submission to this competition.
