In Old School RuneScape (OSRS), the Dwarf Multicannon is a game-changing tool for efficient Ranged training and speeding up Slayer tasks. Unlocked after completing the "Dwarf Cannon" quest-an easy, requirement-free quest that takes 20-30 minutes-it acts as a deployable turret, firing cannonballs at multiple enemies in multi-combat zones. While cannoning can be expensive (cannonballs cost around 210 OSRS gold each), choosing the right spot balances XP gains, cost efficiency, and even potential profit.

The cannon's unique mechanics make it a favorite: it deals up to 30 damage per shot (35 with granite cannonballs), grants 2 Ranged XP per damage dealt, and doesn't contribute to Hit Points XP-perfect for pures aiming to keep low HP. Below are the best cannon spots for different account types, levels, and goals, from low-level training to high-XP grinding.

1. Lighthouse Basement: Dagannoths (Best for High XP Rates)

The Lighthouse Basement, accessible after starting the "Horror from the Deep" quest, is widely regarded as the top cannon spot in OSRS. Located near Rellekka, this multi-combat zone houses 22 Dagannoths-aggressive, low-defense monsters that spawn quickly, ensuring your cannon fires nonstop.

Dagannoths offer exceptional XP rates, reaching up to 130k Ranged XP per hour with proper gear. Their fast respawn rate means you'll rarely out-kill their spawns, keeping your cannon active throughout your trip. While loot isn't highly profitable, it helps offset cannonball costs: expect medium clue scrolls, high-level seeds (like snapdragon), and occasional alchables.

For setup, place the cannon near the center of the pit for optimal coverage. Wear high Ranged bonus gear (such as black d'hide) to boost accuracy, and bring 2,000-3,000 cannonballs, cost-effective food (like pineapple pizzas), and prayer potions for Protect from Melee. Stand near the ladder to safe-spot most damage, and use the nearby upstairs bank to restock quickly.

2. Rock Crabs (North of Rellekka): Ideal for Low-Level Players

For new players or low-level accounts (1-45 Ranged), Rock Crabs on the northern shore of Rellekka are a fantastic starting point. These level-13 monsters have 50 Hit Points but extremely low defense, making them perfect for early cannon training right after unlocking the Dwarf Cannon.

Rock Crabs offer steady XP rates of 50-60k Ranged XP per hour, with minimal risk. They are non-aggressive but respawn quickly, and their high HP means the cannon can fire continuously without frequent respawn waits. This spot requires no additional quest requirements beyond the "Dwarf Cannon" quest, making it accessible to all new players.

Setup is simple: deploy the cannon near the crab spawns, bring a small stack of cannonballs (1,000-1,500 is enough for a short trip), and basic food. Since Rock Crabs deal very little damage, you can semi-afk here, focusing on other tasks while the cannon does the work.

3. Catacombs of Kourend: Versatile for All Levels

The Catacombs of Kourend is a sprawling dungeon with diverse cannonable monsters, making it a versatile choice for players of all levels. This multi-combat area features Bloodvelds, Ankou, and Greater Demons-all of which are ideal for cannoning, with varying XP rates and loot potential.

XP rates here range from 70k-90k Ranged XP per hour, depending on the monster you target. Bloodvelds are a top pick for mid-level players (45-75 Ranged) due to their low defense and fast spawns, while Greater Demons offer slightly higher XP for higher-level accounts.

The Catacombs' biggest advantage is its convenience: it's close to a bank via the Kourend Castle Teleport, allowing quick restocks. Bring a bonecrusher necklace to handle bones and reduce inventory clutter, and use Protect from Melee to stay safe while the cannon fires.

4. Ice Trolls (North of Jatizso): Profit-Focused Cannoning

For players looking to offset cannon costs, Ice Trolls north of Jatizso are an excellent choice. Accessible after completing the "Fremennik Trials" quest, these level-100+ trolls drop valuable loot that often covers the cost of cannonballs.

Ice Trolls offer moderate XP rates (60k-70k Ranged XP per hour) but shine in profitability. Their drops include runes, alchables, and occasionally rare items, making this spot ideal for ironmen or players on a budget. They are aggressive, so safe-spotting is key-use the coal rocks west of the eastern mining icon to avoid damage.

Bring prayer potions, food, and runes for Telekinetic Grab to collect loot without moving. The cannon's high damage output helps take down these tough trolls quickly, and the consistent spawns ensure your cannon stays active.

5. Ogres (East of Castle Wars): Low-Requirement Option

Ogres east of Castle Wars are a great choice for players who want to cannon without additional quest requirements (beyond "Dwarf Cannon"). These level-62 monsters are in a multi-combat zone, with dense spawns that keep the cannon firing steadily.

XP rates here are around 40k Ranged XP per hour from the cannon alone, making it a solid mid-level option. While they can be crowded, switching to a less populated world fixes this issue. Ogres drop basic loot like coins and herbs, which helps offset some cannonball costs.

Setup is straightforward: deploy the cannon in the center of the ogre spawn area, bring enough cannonballs, and wear basic Ranged gear. Since ogres deal moderate damage, bring food or use Protect from Melee to stay safe during longer trips.

Key Tips for Effective Cannoning

No matter which spot you choose, these tips will maximize your efficiency: Always wear your best Ranged gear to boost cannon accuracy-Ava's Assembler (unlocked from Dragon Slayer II) is a game-changer, as it automatically picks up cannonballs and ammunition.

Budget wisely: Cannonballs can cost up to 1.26m gp per hour in top spots, so prioritize spots with loot to offset costs. Granite cannonballs offer higher damage but are more expensive, so use them only for high-XP grinding. For a better gaming experience, it is essential to have a sufficient supply of cheap RuneScape gold.

Use multi-combat zones exclusively-cannons only fire at one enemy in single-combat areas, wasting cannonballs and reducing XP rates. Finally, switch worlds if your spot is crowded; empty worlds ensure maximum cannon uptime and XP gains.

The Dwarf Multicannon is one of OSRS's most powerful training tools, and these spots cater to every playstyle-whether you're a low-level new player, a high-level XP grinder, or a profit-focused ironman. With the right setup and location, you'll blast through Ranged levels and make the most of your cannon investment.
