Bastard Sword Location in Castlevania: Belmont’s Curse (Justice District Sewers)

The Bastard sword is the second one-handed sword most players will find in Castlevania: Belmont’s Curse. It replaces the starting Longsword with double the ATK, and it keeps the same moveset. It sits at the far end of a short but hazard-heavy platforming run in the sewers under the Court of Justice. Once you know the route, you can reach it in a few minutes from the nearest Mirror of Life.

Quick answer: Teleport to the Paris Streets Mirror of Life by the Court of Justice. Head right to the Docks, drop into the Justice District Sewers, clear the grapple section, then double back left to the chest.

Bastard sword requirements

The sewers only open up after you have pushed far enough into the story to return to the surface of Paris. In practice, that means you need the following.

Progress through the Catacombs of Paris and unlock its gate.
Beat the bosses that stand in the way of that progression.
Meet Death, which opens your access to the surface streets.
Have the Arcane Whip, which you need for the grapple rings and hooks in the sewers. It is granted in the Abandoned Sewers in Paris Streets.

Route to the Justice District Sewers

Start from the Mirror of Life that sits near the Court of Justice and the Burned District in Paris Streets. From there, the whole trip runs to the right until you reach the sewer entrance under the Docks.

Open the map and fast travel to the Mirror of Life in the Burned District of Paris Streets. This is the closest teleport point to the Court of Justice.

Leave the mirror and run right across the Bridge of the Millers. The city below is on fire, but the bridge itself is a straight run.

Enter the Court of Justice and keep moving right. Guards and winged enemies patrol the upper battlements and broken buildings here, so clear them as you go.

On the far-right side of the upper ramparts, smash the floor barriers and drop through a vertical shaft to the lower chambers.

Exit right onto the outside balcony above the Docks. Run across the Docks until you reach the opening that leads down.

Justice District Sewers platforming to the chest

The sword sits in a room you can’t reach directly. You have to climb through a separate trap room first and then loop back over the top. Spiked floors and spinning wheels are the only real threats, so take the jumps slowly.

Inside the sewers, break down through the wooden floor grating. A spinning saw wheel sits right next to it, so keep your distance as you drop.

Use the Arcane Whip on the grapple points to swing past the spinning spiked wheels. Don’t touch the floor below, which is lined with spike traps.

Use the grappling rings, suspended hooks, and climbable surfaces to make your way through the remaining puzzle. The large waterwheels covered in spikes pose the greatest danger in this section.

Go through the doorway on the right into the next, higher room. If you open the map here, your marker should sit directly under the chest platform.

Turn back left along the raised catwalk that runs over the big spinning spiked wheel. This loops you around to the platform you couldn’t reach from below.

Unlock the purple-and-gold ornate chest on the wooden platform over the cogwheel; it contains the Bastard sword.

How to confirm you have the Bastard sword

Opening the chest shows the weapon’s card, marked Refined with ATK 50, plus its description and special move. You can equip it right from that prompt by holding the equip button. Later, you’ll find it in the Armoury tab of the equipment menu next to your other weapons. With it equipped, your basic slashes can still break wooden barriers, just like the Longsword.

Bastard sword stats compared to the Longsword

Both swords are one-handed weapons and share the same combo finisher and special move. The Bastard sword is the tier 2 version of the starting Longsword. Its only differences are higher damage figures and better rarity.

Stat	Bastard sword	Longsword
Rarity	Refined	Ordinary
Tier	2	1
ATK	50	25
Attack power	26	20
Mana per hit	3	3
Stagger power	30	30
Combo finisher	Dash through	Dash through
Found in	Paris Streets	Starting weapon

Bastard sword doubles the Longsword’s ATK and raises attack power, while mana per hit and stagger power stay the same. Switching costs you nothing in MP economy and you don’t need to relearn anything. The game pitches it as a balanced weapon built around mobility.

Longsword is the tier 1 weapon of the same family. Once you have the Bastard sword, the Longsword offers nothing extra, since both have the same moves.

The special move rewards repositioning. If you attack right after a backdash or slide, that hit deals bonus damage. So the most efficient way to use the Bastard sword is to slip out of an enemy’s swing and then punish immediately. The Dash through combo finisher keeps you moving through targets instead of standing in place.
