Research Hall

Bloodborne guide · After defeating Ludwig, the Accursed

The Research Hall is a massive, multi-tiered facility within the Hunter's Nightmare populated by deformed, enlarged-head patients. Players must navigate a spiraling network of staircases and platforms to reach the top level and operate a mechanism that raises the central staircase. Altering the stairs grants access to the Lumenflower Gardens, the arena for the Living Failures boss fight.

Tips

Beware of the pool of fluid on the lowest floor, as poisonous or toxic hazards and crawling patients lurk around the central pillar.
Look out for hanging bodies and patients hiding behind corners or doors, as they frequently ambush players in narrow corridors.
Rotating the central staircase alters access to several floors, cutting off old routes while revealing new shortcuts and items.
