Find the Rosary Cannon in Hollow Knight Silksong’s High Halls treasury. Complete guide to this unique gatling gun tool, its location, stats, and strategic uses.
While most tools in Hollow Knight: Silksong serve practical exploration or combat purposes, the Rosary Cannon stands apart as something entirely different – a magnificent, resource-hungry gatling gun that prioritizes spectacle over efficiency. Hidden within High Halls‘ secret treasury, this unique tool represents Team Cherry’s playful approach to late-game content, offering players a chance to literally fire their hard-earned currency at enemies.
The Rosary Cannon embodies the “rule of cool” in weapon design. Sure, it might drain your Rosary reserves faster than a merchant’s clearance sale, but few gaming experiences match the satisfaction of mowing down ground-based enemies with a rapid-fire barrage of spinning prayer beads. This isn’t just a tool – it’s a statement piece.
Tool Classification: Ranged Combat Specialist Ammunition Type: Rosary Beads (up to 80 capacity) Reload Method: Bench interaction required Primary Targets: Ground-based, stationary enemies Strategic Role: Fun factor over practical efficiency Discovery Difficulty: Moderate (requires Simple Key and secret navigation)
Unlike conventional Silksong tools that serve multiple purposes, the Rosary Cannon fills a very specific niche – providing overwhelming firepower against appropriate targets while consuming significant resources. It’s the gaming equivalent of bringing a rocket launcher to a knife fight: unnecessarily excessive, but undeniably entertaining.
Essential Requirements:
Before beginning your treasure hunt, ensure you have a Simple Key available. These valuable items unlock various special doors throughout Pharloom, and the High Halls treasury represents one of their most rewarding applications.
Consider your current Rosary situation as well. While finding the cannon doesn’t require ammunition, actually using it effectively demands a healthy currency reserve. If you’re running low, consider some Rosary farming before diving into gatling gun combat.
Starting Point: High Halls Hub Navigate to High Halls and locate the area’s central hub containing the Ventrica fast travel point and bench. The locked door you’re seeking sits prominently to the left of these landmarks, marked with a distinctive Rosary Necklace icon that hints at the treasures within.
The icon serves dual purposes – identifying the door’s unlock requirement while foreshadowing the Rosary-themed rewards hidden behind it. This visual storytelling exemplifies Silksong’s attention to environmental narrative details.

Key Application and Initial Entry Use your Simple Key on the marked door to reveal what initially appears to be an empty chamber. This apparent emptiness represents the first layer of the treasury’s security – casual explorers might assume they’ve found everything and leave disappointed.
The Secret Ascension The real treasure hunt begins with careful ceiling examination. Look for breakable sections in the chamber’s roof and destroy them to reveal hidden passages leading upward. This vertical exploration requirement tests your thoroughness and willingness to question environmental assumptions.
The Underground Network Once through the ceiling breach, you’ll enter a network of tunnels filled with various obstacles and hazards. This underground complex serves as both protective maze and puzzle, requiring careful navigation to reach the true treasures hidden within.

Navigate cautiously through the tunnel system, watching for environmental dangers that guard the treasury’s contents. The path complexity ensures that only dedicated explorers will discover the chamber’s full secrets.
The Critical Intersection Choice Eventually, you’ll reach a significant junction offering two distinct paths:

Upward Route: The Rosary Bead Bonanza Taking the ascending path leads to a chamber filled with Rosary beads – a substantial currency boost perfect for players building their reserves. This treasure room provides immediate practical value and might tempt players to conclude their exploration here.
Downward Route: The Cannon’s Domain For Rosary Cannon seekers, the descending path leads toward your ultimate goal. This route demonstrates the treasury’s layered design, where different treasures require different levels of exploration commitment.
Environmental Navigation Following the downward path brings you to a steam-filled chamber with limited safe platforms. This area tests your platforming skills while building tension toward the final discovery. The industrial atmosphere contrasts sharply with the ornate treasury above, creating environmental variety within the complex.
The Hidden Wall Revelation On the chamber’s main platform, examine the left wall carefully for breakable sections. Destroying this concealed barrier reveals yet another seemingly empty room – the pattern of hidden spaces continues, testing your persistence and observation skills.
The Final Secret: Ceiling Surprise In this new chamber, look upward to spot a breakable object attached to the ceiling. This final concealment mechanism protects the Rosary Cannon from casual discovery. Destroying the ceiling attachment causes the gatling gun to tumble down, creating a satisfying moment of revelation after your extended treasure hunt.
Tool Acquisition Interact with the fallen Rosary Cannon to add it to your arsenal. The glowing item pickup provides visual confirmation of your successful treasure hunt while adding this unique tool to your combat options.
Bench Configuration Return to any bench to equip the Rosary Cannon and examine its specifications. The tool’s 80 Rosary bead capacity and bench-required reloading immediately distinguish it from other combat options, setting clear expectations for its operational requirements.
Optimal Target Profile:
Tactical Considerations:
Ammunition Economics: Each shot consumes a Rosary bead, making prolonged firefights expensive. Consider the cost-benefit ratio before engaging challenging enemies that might require extensive ammunition expenditure.
Reload Logistics: The bench-required reloading creates strategic pressure to maximize each ammunition load’s effectiveness. Plan your routes around bench locations when intending heavy Rosary Cannon usage.
Situational Deployment: The cannon excels in specific scenarios but struggles against aerial enemies or highly mobile opponents. Recognize when to switch to more versatile tools for optimal combat efficiency.
Fun Factor Priority The Rosary Cannon’s primary value lies in entertainment rather than optimization. It provides a unique combat experience that prioritizes spectacle over efficiency, offering players a chance to experience overwhelming firepower regardless of practical considerations.
Resource Management Challenge Using the cannon effectively requires thoughtful resource allocation and strategic planning. This adds a layer of economic strategy to combat encounters, where ammunition scarcity influences tactical decisions.
Specialized Application Tool Rather than a general-purpose weapon, consider the Rosary Cannon a specialized solution for specific encounter types. Its niche effectiveness against appropriate targets can make it surprisingly valuable in the right situations.
Cost Analysis:
Sustainable Usage Strategies:
Vendor Encounter During your treasury exploration, you’ll encounter Grindle, a familiar merchant character who’s clearly been exploring the chamber’s contents himself. This meeting provides both narrative flavor and practical utility.
Missed Tool Recovery Grindle’s presence offers a safety net for completionist players – missed tools like the Magnetite Dice may appear in his inventory, providing second chances for tool collection. This merchant interaction adds practical value to your treasury visit beyond just the Rosary Cannon acquisition.
Practical vs. Spectacular: While tools like the Clawline or Multibinder serve essential exploration and combat functions, the Rosary Cannon prioritizes spectacle and unique gameplay experiences over universal utility.
Resource Requirements: Most Silksong tools operate without ongoing costs, making the Rosary Cannon’s ammunition consumption a unique characteristic that influences its strategic role within your overall toolkit.
Ammunition Conservation:
Combat Integration:
Maximizing Your Visit: Don’t leave the High Halls treasury without thoroughly exploring both the upper Rosary chamber and the lower cannon area. The complex rewards multiple types of exploration, providing both immediate currency benefits and unique tool acquisition.
Future Access: The treasury remains accessible after your initial visit, allowing return trips for additional Rosary collection if needed. This accessibility makes the location valuable for ongoing resource management throughout your Silksong journey.
The Rosary Cannon represents Team Cherry’s willingness to include content that prioritizes fun over optimization. In a game filled with precisely balanced tools and abilities, this gatling gun offers pure, unapologetic excess that rewards players willing to embrace spectacle over efficiency.
While it may not become your primary combat tool, the Rosary Cannon provides memorable moments and unique tactical options that enrich the overall Silksong experience. Sometimes, the best tools aren’t the most practical ones – they’re the ones that make you smile while using them.
Whether you’re clearing corridors with rapid-fire Rosary barrages or simply enjoying the absurdity of a prayer bead gatling gun, the Rosary Cannon proves that even practical metroidvania adventures have room for pure, joyful excess.
