What Are Dwarf Cannon Osrs Maintenance Costs And Fees?
Before investing in a Dwarf Multicannon for Old School RuneScape skilling, what's the realistic ongoing upkeep? Does the gp drain come from buying cannonballs or repairs?
That's more of a game mechanics question for Old School RuneScape, not a story topic. Those costs can change with game updates, so it's best to check the official wiki for the latest numbers. For a different kind of heavy maintenance, you might check out the fantasy web novel 'Owned by the Dragons', where the human protagonist has to constantly manage the demands and territorial politics of three possessive dragon lords to survive. It's less about gold fees and more about the cost of keeping powerful, jealous beings appeased.
I get a little giddy talking about this because the dwarf multicannon is such a simple, satisfying gadget in 'Old School RuneScape'. The short version of costs: you pay once for the cannon itself and after that the only real recurring expense is cannonballs. You buy the cannon from the dwarf located at the Dwarf Cannon shop for 7,500 coins (that’s the one-time purchase). Once it’s placed, it doesn’t require repairs or upkeep — it won’t wear out — but it does need cannonballs to actually shoot.
Maintenance in practical terms is all cannonball-related. The cannon holds 30 cannonballs per full load, so your short-term cost is 30 × price-per-cannonball. How many full loads you burn depends on the spawn density and how long you leave it running; at busy slayer or training spots you might go through several loads an hour. To save gold I often make my own cannonballs at a furnace using steel bars (you usually get multiple cannonballs per bar), or I wait for cannonball prices to dip on the Grand Exchange. For me, the cannon is worth it whenever I can turn the increased kill rate into XP or loot that outweighs the ammo cost — it feels like renting extra hands, and I love that mechanical simplicity.
I still treat the cannon like a tiny army companion: buy once, feed with cannonballs. The one-time purchase from the dwarf vendor is 7,500 coins, and after that the only maintenance cost is ammunition. The cannon uses up to 30 cannonballs per load, so do the quick math: price per load = 30 × cannonball price. If cannonballs are cheap, the cannon becomes extremely cost-effective for fast XP and clearing crowds.
To keep fees down I either craft cannonballs at a furnace when I can or wait for low Grand Exchange prices and buy in bulk. Also, placing the cannon at dense monster spawns means you burn through fewer loads for the same XP, so your gold-per-XP ratio improves. I often leave mine running at efficient spots and it feels like getting free extra hands — still one of my favorite QoL tools in the game.
I still smile when I set one up because it turns chaotic skirmishes into controlled mayhem. Practically speaking: buy the cannon once (7,500 coins from Nulodion), then keep buying cannonballs. A full load is 30 cannonballs, so maintenance math is straightforward: cost per load = 30 × market price per cannonball. If cannonballs are 120 gp each, one load costs 3,600 gp; if you burn through, say, 4 loads in an hour at a crowded spot, that’s 14,400 gp for ammo that hour.
If you want to reduce fees, make cannonballs yourself at a furnace if you have bars and a mould, or buy in bulk on the market when prices slump. Also place the cannon at high-density spawns so your gold-per-hour on ammo converts into XP or drops that actually make money back. I usually check the current cannonball price and consider whether the extra kills will cover the ammo before I set it up.
Lately I’ve been thinking more about efficiency, so I break the cannon costs down into concrete pieces and tactics. First, the entry cost is tiny compared to long-term ammo expenditure: the cannon costs 7,500 coins up front. From then on the main budget line is cannonballs. One useful mental model I use: treat a single full load (30 cannonballs) as your unit of use. That gives me quick comparisons — for example, a 30-ball load at 150 gp each is 4,500 gp, and if I expect to use three loads in a typical training session, I’m budgeting ~13,500 gp for ammo.
Beyond that, I pay attention to two levers. One lever is sourcing: crafting cannonballs at a furnace (using steel bars and a mould) often cuts costs if I have the materials or access to the Blast Furnace to be efficient. The other lever is placement: the more efficiently the cannon converts ammo into kills or valuable drops, the better the return. There aren’t ongoing hidden fees like repair or daily taxes — it’s basically buy the cannon, buy the ammo. I like to think of it as an investment in time: spend gold on cannonballs to buy more AFK-able training and faster kill rates, and then tweak where I set it for the best net gain.

The Boss Billed Me For My Own Building
Perfect Timing

On the first day of work, my boss, Wayne Richmond, gives everyone a nice bonus to start the year.
Some receive 100 dollars, while others receive 200 dollars.
When it's my turn, all I get is a piece of A4 paper. The rent, the management fee, and the utility bills, all from last year, are printed on the paper.
At the end, I see Wayne's bank account number listed there.
Wayne just looks at me haughtily as he says, "Meredith, you took the liberty to take on overtime shifts that last for more than a thousand hours last year. But despite the long hours, you didn't really bring much profit to the table.
"That's why you should be the one paying for the property fees and the utility bills, seeing as you've wasted so much resources. This shouldn't be an outrageous request, right?"
When I try to argue with Wayne, he just waves a hand at me impatiently.
"I'm already charging you the lowest rate. Hurry up and pay the bills. Don't delay the work hours for everyone."
As I stare at the piece of paper, I just smile instead of lashing out at Wayne.
Everyone in the company doesn't know that I'm actually the owner of the building this company is based in.
That means Wayne is giving me, the owner, the bill that he's supposed to be paying.
In that case, I shall be retrieving every single cent that I've spent on this company.
I won't be playing nice anymore.
My father loved silence. He believed noise was the mark of lesser people, so he installed a decibel meter in our home.
Speaking above 40 decibels meant that we would have to pay him 10 dollars, laughing above 60 decibels meant 50 dollars, and crying or throwing a tantrum was a serious offense at 100 dollars per second.
The year I turned four, I fell and broke my arm. I did not make a single sound. I bit down so hard that I cracked two teeth, but I saved thousands in noise fees. He praised me for it and called me a "high-value child," one that was worth the investment.
I treasured that compliment and observed the rules carefully, keeping the house wrapped in suffocating silence.
Then came the stormy night a thief broke in. He had a knife and was creeping toward my mother as she slept, and I watched it all from the gap in the wardrobe where I was hiding.
I wanted to scream. I wanted to shriek and wake my father, to do something, anything. However, my eyes drifted to the decibel meter on the wall, and my hand found nothing but an empty pocket.
I did not have enough allowance. One scream would cost hundreds, and I simply could not afford it.
After ten years studying interior design overseas, I came back to my hometown to do work that mattered to the people who raised me.
I offered the full package, from site survey to soft furnishings. The materials were chosen by hand. The price was fair to the bone.
The town had just gone through a redevelopment. Everyone was getting new units. With the new family policy, every family wanted a third bedroom too. My business was good. Customers from the next county were driving in.
Then a girl just back from a city college kicked open my studio with her phone on a livestream and her neighbors at her shoulder.
"This is the dishonest one. Look at her. She has been ripping the village off."
"In the city, an eighty-square-meter unit can be done for twenty thousand dollars. She is charging eighty."
"That's a sixty-thousand-dollar margin. Sixty thousand. Right out of our pockets."
The village fell in line behind her. They demanded the difference back. When I refused, they smashed my studio. They beat me into a coma. The pile-on online killed me.
When I opened my eyes again, I knew exactly what I was going to do.
I would refund every single one of them. And then I would tear out every single thing I had installed.
Let's see what twenty thousand dollars actually buys you.
Since I've spent a few minutes using the toilet during work hours, I only receive 3500 dollars despite my salary being 20 thousand dollars.
I confront my boss, Vivian Dune, immediately. Although she seems fair and just on the outside, she adopts a passive-aggressive attitude with me.
"The security footage from last month shows that you've used the toilet for 40 minutes altogether. Don't tell me you're working there, right?
"It'll be 500 dollars for every minute you spend in the toilet. That's the new rule of the company. Since you're a veteran employee, you should be the one taking the lead. Honestly, I already went easy on you."
I'm a veteran employee who has been working at this company for ten years. Each business deal that I've closed brings the company at least 100 million dollars worth of revenue.
But now, I get robbed of my most basic right as a human.
Seeing my lack of response, Vivian flashes me a venomous smile.
"If you really don't want to work here, you might as well leave. Do you seriously think we need you? Don't forget that your five-year contract isn't up yet. Who in this industry will want to hire you next?"
I don't argue with her any further. But when my contract, which only has five days left, comes to an end, she's the one panicking instead.
The Intern Regrets Forcing Me To Pay 700,000 Dollars

At the New Year’s team-building event, the intern, Lilith Woods, did not obtain my approval and changed our suburban trip to a seven-day tour of Baline.
“Mr. Lucian Stone, I hear a change of scenery can really spice things up. Don’t lock up tonight. I’ll come by for a deep dive into our collaboration.”
She pretended to be drunk and fell into my arms while slipping the room key into my pocket in the process.
To avoid suspicion, I did not return to the hotel. However, in the middle of the night, the police called me in for questioning—someone had reported a dine-and-dash.
Only then did I realize that the reserved budget of $100,000 for the accommodation had long since been exceeded.
Lilith had upgraded their room to a presidential suite, feasted on high-end seafood buffets, and even used company funds to buy luxury handbags!
When I showed up at their private room, the interns were still casually taking king crabs and several unopened bottles of the Macallan Whisky with them.
“Mr. Stone, you’re just in time. Could you please settle the bill?”
Lilith looked utterly righteous as she said this with a grin.
“Young people like us make mistakes, while adults help to pay the price. You’re not exactly short on cash, anyway. Just think of it as buying my happiness.”
I stared at the $700,000 bill and paid it in silence.
The next day, the payment invoices made their grand entrance in the group chat, accompanied by my pinned message.
[Upon financial review, this team-building event does not meet reimbursement criteria. All expenses will be shared equally among the seven participants.]
[Each person will need to pay $100,000, payable immediately. If payment needs to be deferred, please print the proof and submit it to the President’s Office.]
I always had a weakness for handsome men, so I camped out online to grab one of the very first AI incubi.
The brand's whole pitch was seduction tuned a hundred percent to its owner's taste. But every time I got within ten minutes of Lucien Crane, he'd force-start a system cleaning cycle, go dark, and idle out.
"Master, please don't overuse me. Bacteria buildup can cause a malfunction."
Left unsatisfied every single time, I finally went to customer service, and the rep looked as baffled as I felt.
"An incubus unit would never break off contact with its owner. We'd recommend restarting him at home."
But on the drive back, I happened to scroll past a livestream from my live-in housekeeper. The title sat right there in bold: How a Seasoned Queen Subdues In Her AI Incubus.
The lighting was low. The man's earlobes were flushed, and he knelt on one knee, every inch of bared skin crossed with messy whip marks.
My housekeeper wiggled her red-painted toes, all smiles.
"This one's got real stamina. Five hours straight and he never once tapped out."
As the comments poured in, envious, a chill ran through me.
So the so-called "cleaning system" was just his excuse to slack off and idle.
Behind my back, he was happily playing somebody else's obedient little sub.
If he wouldn't serve me the way he was built to, then he could wait to get shipped back to the factory and scrapped for parts.
I got way into tinkering with the dwarf cannon back when I was skilling and PvM-ing a lot, so here's the straightforward breakdown I use when planning a session.
To build a cannon you need the four cannon parts: the base, the stand, the barrels, and the furnace. You can buy those parts directly from the dwarf vendor in the Dwarf area for a fixed in-shop price (so you don’t have to mess with the Grand Exchange if you don’t want to). Expect to pay roughly a few thousand GP per part depending on the economy—so a rough ballpark for a fresh build from the dwarf is around 8k–12k GP total. If you buy an assembled cannon on the Grand Exchange instead, prices are volatile but usually higher because people sell as a single item.
Repairing a cannon is effectively replacing damaged parts or simply rebuilding it; the dwarf sells replacement parts at the same fixed prices. The recurring cost that really adds up is ammo: cannonballs are the big ongoing expense. A typical firing rate burns through roughly 30 cannonballs per minute (so about 1,800 per hour); at ~2 GP per cannonball that’s on the order of 3.5k–4k GP per hour. You can reduce ammo cost by crafting your own cannonballs from steel bars (1 steel bar → 4 cannonballs) if you’re into smelting and want to cut costs. Personally I plan for the initial ~10k build and then expect an hourly ammo burn of a few thousand GP depending on how long I let it fire — that’s been my rule-of-thumb for budgeting cannon runs.
Sliding a dwarf multicannon into place in 'Old School RuneScape' always feels like setting up a tiny, noisy guardian that does all the dirty ranged work for me. I assemble the parts, plunk it down where the spawn angles are generous, and load it with cannonballs. Once it's loaded and fired it automatically spits projectiles in an arc, hitting any monsters that walk into its firing cone. I tend to leave it to chew through groups while I pick off stragglers or loot, because it happily handles multi-target pressure without me having to aim or click each mob.
Positioning is everything for me: I like to place it where the most spawns will walk through the cone, and where I can safely kite or stand ready to finish off survivors. It burns through ammo, so keeping an eye on cannonball supply is part of the rhythm — I top it up between waves. It’s wonderful for slayer tasks and multi-spawn areas; every time it clatters away I feel like I’ve hired a tiny, efficient mercenary. Definitely one of my favorite lazy-combat toys in the game.
Let's get your dwarf cannon set up step by step the way I do it when I want efficient monster clearing. First, get a full cannon or the five separate parts: base, stand/legs, furnace/body, barrels, and a supply of cannonballs. You can buy a whole cannon or the parts from the dwarf seller in the dwarven area or just grab them on the Grand Exchange. Make sure you have enough inventory space for the parts and at least a stack of cannonballs (the cannon accepts up to 30 at a time).
To set it up, equip or use the base on the floor where you want it and choose 'setup' — that drops the base. Next, use the stand/legs on the base to attach them, then use the furnace/body on the stand. After that, use the barrels on the furnace to complete the assembly. Once the model is fully assembled it will visually look like a cannon. Finally, load cannonballs from your inventory onto the cannon (it will take ammo automatically up to its capacity). Click the cannon and choose 'fire' or let it auto-fire at nearby NPCs; it will target valid monsters automatically. If you need to move it, dismantle by using the cannon parts or the 'pick-up' option in reverse order so your inventory has room. I like to place mine on a safe tile behind my character so the shots land where I want them — nothing beats watching a crowd of goblins get shredded while I sip tea.
