Castlevania: Belmont’s Curse — How to Find the Medusa Boss Location

Medusa sits deep under Holy Innocents’ Cemetery in Castlevania: Belmont’s Curse. Getting to her means working your way down from the surface ruins, through the flooded Roman ruins below, and into the snake-filled tunnels that lead to her arena. The route is long, but it is linear once you know which drops and levers matter. Along the way you pick up two relics, a new weapon, and the four clues that point to her Arcana card, The Prophetess.

Quick answer: Medusa is in the Ossuary of the Innocents district of Holy Innocents’ Cemetery. Reach her by dropping from Pauper’s Grave into the Ruins Entrance, following the Roman Baths to Serpents’ Lair, and resting at the Mirror of Life outside her chamber.

Medusa boss location in Holy Innocents’ Cemetery

Holy Innocents’ Cemetery is one of the City of Paris areas, and Medusa is its only boss. The game places her fight in the Ossuary of the Innocents district. You cannot walk straight there from the surface, though. The way into her chamber runs underground, through the Ruins Entrance, Roman Aqueduct, Roman Baths and Hot Springs, and ends in Serpents’ Lair, where a Mirror of Life waits just outside the arena door.

The cemetery has four Mirrors of Life in total. The route below uses three of them: the one in the Cloister where you start, one in Pauper’s Grave halfway through, and the last one before Medusa.

Route to Medusa from the Cloister Mirror of Life

Start at the Mirror of Life in the Cloister. Open your map once before you move off so you can see how the surface districts connect.

Cloister to the Fountain of the Innocents

Head right from the Cloister mirror into Sepulcher of the Knight. Talk to the spirit there to get the “Roman Baths” clue.

Drop down the vertical shafts lined with spikes. Use the whip on the ceiling rings to swing across the spike pits until you land in Memorial for the Dead.

Fight past the armored enemies in Memorial for the Dead and flip the wall switch. It lowers a bridge that links back to the Cloister, so you can rest at that first mirror before pushing on.

Go right over the upper ruins and stone arches until you arrive at the Fountain of the Innocents. Find the concealed entrance below it and descend to Pillaged Tombs.

Survive the locked combat wave of flying spirits and armored guards. Open the red chest afterward to collect the Nightshade relic, then climb back out to the fountain.

Iron gate, Ossuary and Pauper’s Grave

Keep heading right over the ruined towers and high staircases until you reach an iron gate. Pull the floor lever beside it.

Climb above the gate and open the ornate chest to get the Lance. A large demonic crow attacks at the altar nearby, so be ready to fight it before moving on.

Follow the arched corridors of Ossuary of the Innocents to Pauper’s Grave. Defeat the enemies in the arena room, where a shield protects a green crystal; collect the Attack Up pickup from the upper ledge, then speak with the spirit beside the fountain to get the “Cemetary Fountain” clue.

Go back through the Ossuary and down the outdoor steps into Pauper’s Grave. Rest at the second Mirror of Life there.

Cross the upper ledges into Mausoleum of the Kings and on to Chapel of the Kings. Clear the wave of archers, guards and the large skeleton beast, then speak to the spirit inside the hollow tree for “The Roots of the Hollow Tree” clue.

Underground: Roman Baths to Serpents’ Lair

Return to the Pauper’s Grave mirror and drop down the floor shafts below it. You land in the green-tinted, flooded Ruins Entrance.

Follow the Roman Aqueduct into the Roman Baths, watching for the spinning saw blades. Keep heading east and down.

Clear the locked arena in Mass Grave, where harpies and skeleton archers attack. The chest that opens afterward holds the Raven’s Feather relic.

Work back through the Roman Baths past the conveyor platforms, spike walls and buzz saws. A spirit on a high walkway gives you the “Guardian’s Gaze” clue.

When a gate blocks the route east, loop around it through Hot Springs. Climb the vertical saw section with the grapple rings, then pull the lever in the Roman Baths to open the gate.

In the Hot Springs loop, Chaos Shards cover the floor gaps under the moving saw. Holy Light clears them.

Cross the water and the green caverns east into Serpents’ Lair. Pass through the archway, rest at the Mirror of Life just outside Medusa’s chamber, then go back and take the stairs down into her arena.

You know you are in the right place when a cutscene starts with The Fallen, Rose and Medusa. The fight begins at the water’s edge as soon as it ends.

The Prophetess clues and where each spirit is

The Prophetess is Arcana number 4, and it has four clues. Every one of them sits on the route above, so you collect the whole set without leaving the main path. Note that the game spells the second clue “Cemetary.”

Clue	Where the spirit is	Route step
Roman Baths	Sepulcher of the Knight	1
Cemetary Fountain	Fountain of the Innocents	8
Beneath the Hollow Tree	Hollow tree, Chapel of the Kings	10
Guardian’s Gaze	Upper walkway, Roman Baths	14

Read in order, the spirits point the same way the route does. One says the Captain of the Guard led them into the Roman Baths after the creature. Another warns that anything thrown into the fountain “disappears.” A third lost a sister who “slipped beneath the roots of the hollow tree.” The last describes seeing the monster’s eyes and being unable to move, which is your warning about her gaze.

Lance, Nightshade and Raven’s Feather on the way to Medusa

Three pieces of gear are found in Holy Innocents’ Cemetery along the route. All of them are worth equipping before the fight.

Item	Type	Where	Effect
Nightshade	Relic	Pillaged Tombs	Healing potion restores 40% max mana
Lance	Weapon (Spear)	Above the iron gate	Can be aimed and thrown
Raven’s Feather	Relic	Mass Grave	+25% damage in the air

Nightshade turns every healing potion into a partial mana refill as well, giving back 40% of Rose’s maximum mana each time you drink one.

Lance is a tier 1, Ordinary spear. Hold the attack button to aim it, then let go to throw it, which gives Rose reach on targets she cannot get close to. Its combo ends in a Push finisher.

Lance stat	Value
ATK	25
Attack power	22
Stagger power	30
Mana per hit	3

Raven’s Feather boosts Rose’s damage by 25% during aerial combat.

Medusa boss stats and immunities

Medusa has 1,500 health and a fixed base value, so there is no difficulty setting that changes it.

Stat	Value
Health	1,500
Attack	24
XP	500
Arcana card	The Prophetess
District	Ossuary of the Innocents

Several crowd-control effects do nothing to her. She is immune to:

Petrify, freeze and fatal fall
Launch into the air and slam down
Chronomantic Dive slow
Freezing Path link
Infernal Pyre launch

Medusa is one of three bosses that drop a key for the sealed Catacombs door. Here is how she lines up against the other two.

Boss	Area	Health	Key reward
Leon	Paris Streets	800	The Fallen’s Key
Medusa	Holy Innocents’ Cemetery	1,500	The Prophetess’s Key
Joan	Paris Streets	1,800	The Warrior’s Key

Medusa rewards: Petrifying Gaze and The Prophetess’s Key

Beating Medusa seals her into The Prophetess card and gives you two rewards plus 500 XP. You can confirm the fight counted by checking your key items for The Prophetess’s Key and your spells for Petrifying Gaze.

The Prophetess’s Key counts as one of the three keys needed to unlock the sealed Catacombs door. Once you possess the other two, you can enter through it.

Petrifying Gaze turns enemies standing in front of Rose to stone. The spell uses 75 mana and has 25 attack power. Its gifts improve its efficiency over time. Defeating a petrified enemy restores half the spell’s mana cost, and foes closer to Rose remain petrified longer and need more hits to break free.

The Prophetess also has two works of mercy tied to the spell. One asks you to petrify an enemy carrying a shield. The other asks you to petrify 25 enemies in the air and have each one die from the fall right after.
