Lost Amygdalan Arm — Bloodborne

Find a copy

First obtain the normal Amygdalan Arm. Its entry explains where to find it in The Old Hunters. Acquiring it unlocks the Lost variant at the Chalice Bath Messengers.

Descend to layer 4 of the fixed Lower Pthumerian Labyrinth. From the lever room, enter the room on the right and reveal the hidden passage behind the wall; the Messengers are beyond it.

Buy the Lost variant for 66000 Blood Echoes. The merchant offers it only after you obtain the corresponding normal weapon.

Alternative glyph route

Published alternative: glyph 8i29rqz3, Pthumeru Root, layer 1, main area. Own the Pthumeru Root Chalice to search for this dungeon from a Hunter’s Dream altar, then find the Chalice Bath Messengers.

Glyphs are published references from Bloodborne Wiki and have not been tested online here. Shared dungeons can expire; if the search fails, use the route without a glyph described in this entry.
