The Brine Cellars, Hollow Hill Warrens and Knoll Delvings have new layouts. The Brine Cellars descends from a salt cellar into the sea. Hollow Hill is a set of winding burrows that breaks into an old Order cellar. Knoll Delvings is a mine that drops into a barrow and climbs to a furnace.
Each delve changes light, fog and air as you move between its parts.
Old Barrelback lives in an oil cask. He rears up when his belly is open. The sea floods his cave as the fight goes on.
Gobbo Smeltmaw's bellows glow while he overheats, and the stagger bar now fills and shows the break.
Winch plates light up as players stand on them. Ore carts and pillars give cover from Rattlejaw's volley.
Every delve has its own music, and each boss fight gets action music that speeds up and builds with each phase. The other dungeons now use the music of their nearest theme until they get their own.
