TheWoWDBRaid - Midnight
The Tidebound Grotto
1 encounter, 15 boss abilities and 13 drops, with the Adventure Guide’s own ability and strategy notes for each fight. Every drop links to its item page; tradeable drops carry a live Auction House price.
Hidden beneath the waves of Atal'Utek lies the Tidebound Grotto, a submerged cave veiled by shifting tides. Within, the naga sorceress Nymrissa Wavecaller bends the tides to conceal her domain--and to drown any who dare uncover it.
