Where to Find the Rosary Cannon in Hollow Knight Silksong

You’ll come across the Rosary Cannon much later in your journey, hidden inside the High Halls region. The weapon is locked behind a sealed door that requires a Simple Key to open.

There are two main ways to obtain this key:

• Bone Bottom Merchant – After passing the Chapel Maid, head into Bone Bottom town. The merchant here sells a Simple Key for 500 Rosaries.
• Jubiliana in Songclave – Another option is to buy the key from Jubiliana for 650 Rosaries, making it a slightly pricier choice.

Once you’ve secured the key, return to the locked door in High Halls, use it to open the passage, and prepare for a challenging platforming section.

Traversing the Path to the Rosary Cannon

To reach the cannon, you’ll need both the Clawline and Drifter’s Cloak abilities. The path is mostly vertical, with tricky wall jumps, platform climbs, and narrow descents. Enemies are scattered along the route, but many can be skipped if you focus solely on movement.

At the lowest section, you’ll find a lever that grants access to a hidden chamber. Inside, another ceiling-mounted lever releases the Rosary Cannon for you to claim.

After picking it up, return to the nearest Bench and equip it by holding down Y (Xbox controls) to activate it on your crest loadout.

How the Rosary Cannon Works

Once equipped, the Rosary Cannon transforms into a high-speed ranged weapon:

• Attack Style: Fires a continuous stream of Rosaries, similar to a minigun.
• Slot Usage: Occupies a red crest slot.
• Damage: Extremely high, especially effective against groups and tough enemies.
• Cost: Each shot consumes ammunition, so managing resources is key.

This makes the Rosary Cannon one of the best weapons in Hollow Knight Silksong, perfect for players who want heavy firepower and a safer ranged option against dangerous foes.

The Rosary Cannon is more than just a late-game upgrade—it’s a game-changer for Hornet’s combat style. By mastering the parkour challenges of High Halls and securing the Simple Key, you’ll unlock one of the most versatile and destructive weapons in the game.
