The Hollow Bone is a relic in Castlevania: Belmont’s Curse that rewards whip swings on anchors with extra running speed. It is tucked away in the Clock Tower, a short trip from a save point.
Quick answer: In the Clock Tower, locate the little chamber on Daedalus Crossing’s western side and open the chest at its extreme left. Sprint through when the falling stone slabs leave an opening. Mechanic’s Ascent has the closest Mirror of Life.
Where the Hollow Bone is
A dark chest sits along the room’s leftmost wall. Enter the chamber through the doorway on the left side of Daedalus Crossing’s large hall.
- Area: Clock Tower
- District: Daedalus Crossing, through the left door of the main hall
- Container: dark chest at the far left end of the small room
- Hazard: Chains suspend massive stone blocks, which crash down onto the floor at the room’s center
- Nearest Mirror of Life: Mechanic’s Ascent

What the Hollow Bone does
After Rose spends 5 seconds using the whip on an anchor, her movement speed rises by 35%. The card reads:
“Rose’s movement speed is increased by 35% after using the whip on an anchor for 5 seconds.”
Its flavour text adds: “Preserved in a cabinet of curiosities, this avian relic defies all natural classification.”

You can equip it straight from the card with Hold to equip, or later from the Equipment screen. It fits routes with lots of whip anchors. To compare it with other relics, check how the relics rank.
