Introduced in Update 11.70
RAID Proving Grounds turns restricted Champion Pools into rotating boss puzzles
The level-60 mode uses 27 one-round boss-pair stages, rotating Champion Pools, limited daily keys and Anomalous Accessories.
Proving Grounds gives level-60 accounts a rotating roster challenge. Its 27 stages pair bosses in a single round while Champion Pools and multipliers restrict which solutions can enter.
Daily attempts reward diagnosis
The published structure provides three Proving Keys and three Rematch Keys each day. Use the first attempt to identify the failing mechanic, then spend a rematch on one deliberate team, preset or build change.
The mode runs on a 28-day rotation and rewards Anomalous Accessories. Review the current Pool before investing in a specialist, because the legal roster and multipliers define the puzzle as strongly as the bosses themselves.
