A repurposed rosary stringing machine that fires your own currency as a stream of bullets.
The Rosary Cannon turns Silksong's currency into ammunition, spraying roughly ten Rosaries a second in a stream that doubles as a minigun.
It is a Red Tool, the attack category, built from a repurposed rosary stringing machine. The wiki notes Hornet stands still to pull it out and starts firing after a short delay, with recoil pushing her backward.
The catch is the cost. Every shot spends real Rosaries, and a full reload is the most expensive of any Red Tool, so the cannon is as much an economy decision as a combat one.
This guide covers what the Rosary Cannon does, its exact stats, where to find it in High Halls, the synergies that make it viable, and the reload trap that catches most players.
A Red Tool minigun that fires Rosaries.
High Halls Rosary Bank, opened with a Simple Key.
80 Rosaries per reload, 60% above other tools.
Magnetite Brooch to recover fired Rosaries.The Rosary Cannon fires automatically at roughly 10 Rosaries per second for as long as you hold the input. According to the wiki, each rosary deals either 1 or 2 damage at random, so its output is a steady stream rather than big single hits.
Using it locks Hornet in place. She stands still to deploy the cannon, there is a short wind-up before the first shot, and the recoil pushes her backward as she fires.
That makes it a commitment tool. It belongs in the Red attack slot of a Crest, and it shines when you can plant yourself and hose down a target that cannot punish you for standing still.
The Rosary Cannon's defining stat is its ammo economy, not its raw damage. It holds 80 Rosaries and burns through them fast at ten per second.
| Stat | Value |
|---|---|
| Tool type | Red (attack) |
| Fire rate | About 10 Rosaries per second |
| Damage per rosary | 1 or 2, random |
| Capacity | 80 Rosaries |
| Reload cost | 80 Rosaries (60% more than others) |
Reloading is deliberately awkward. The wiki specifies it must be loaded manually while resting at a Bench, by selecting it in the inventory and holding the attack input.
The reload is the catch. The wiki notes Hornet cannot reload the cannon when she respawns at a bench without Dead Bug's Purse, and it cannot be reloaded through the Architect Crest's Craft Bind, so plan your refills.
The Rosary Cannon sits in the Rosary Bank within High Halls, just west of the Ventrica station. Per the wiki, a Simple Key opens the vault room that holds it.
Reaching High Halls needs the Clawline, the grapple traversal tool, so this is a mid-to-late pickup rather than an early one. Players usually arrive after picking up other tools and a spare Simple Key.
Once inside, the cannon does not just sit on a pedestal. You break the mechanism below the rosary stringing machine with the Needle, which drops it as a collectible.
The Rosary Cannon only becomes practical when you stop the ammo cost from bleeding you dry. The right tools turn its biggest weakness into a non-issue.
Magnetite Brooch (auto-collects the Rosaries you fire) Dead Bug's Purse (keeps your Rosaries on death so reloads survive)
Pollip Pouch (adds poison damage on top of the stream)The Magnetite Brooch is the keystone. In actual play, sweeping your spent Rosaries back up after a fight is what keeps the cannon from draining your wallet faster than your enemies' health.
The Rosary Cannon is a niche pick, not a default. Its damage is fine and its fire rate is satisfying, but the standing-still requirement and the steep reload cost keep it off most general-purpose builds.
Where it earns its slot is on stationary targets and with the recovery synergies attached. Against a 
boss that telegraphs long openings, planting and unloading 80 Rosaries can outpace melee.
Treat it as a specialist. Memory Locket slots are limited, so the cannon competes with steadier Red Tools for a spot in your build.
The Rosary Cannon is one slot in a deep tool system. These guides cover the Crests, slots, and content around it.
