Can I Use Mist Rune Osrs In Slayer Tasks?

Okay, this one gets asked a lot and I used to fall for it too — there’s no such thing as a mist rune in Old School RuneScape. I used to skim forum posts and assume any weird rune name I hadn’t seen before must exist in OSRS, but 'mist rune' is actually a thing from the modern RuneScape side, not the old-school game. In practical terms, if you’re trying to cast a spell or follow a guide that mentions a mist rune, you won’t find it in the shops, on the ground, or at the Grand Exchange in Old School. What you should do instead is use the regular water rune or an elemental staff that provides unlimited water runes. In OSRS, water runes cover the water-element needs that mist runes would in other versions. So, buy water runes from the Grand Exchange, bring a water battlestaff to save on runes, or craft them the Old School way if you’re into Runecrafting. I still get a kick out of clearing up that little confusion whenever I see it on a guide — saves a lot of time and confused bank tabs.

If you're asking about Old School RuneScape specifically, the short reality is: there is no mist rune in OSRS. I had the same confusion a while back because the modern RuneScape (the updated RS3) has combination element runes like mist, dust, smoke and steam, but OSRS sticks with the classic air/water/earth/fire runes. So in OSRS there’s nothing called a mist rune to try to 'stack' with other elemental runes. For clarity, in RS3 the mist rune is a combination rune that can substitute for either an air or a water rune when casting — but it only counts as one component, not both at once. That means even in RS3 you don't get a multiplicative stacking effect; a mist will fill one required rune slot (air or water) but won't double-dip to satisfy two different requirements on the same cast. Personally, I find that design neat because it simplifies bookkeeping without breaking balance, but for OSRS players the takeaway is simple: use the vanilla elemental runes and don't worry about mist stacking here.

If you're grinding Slayer and want to shave time off long tasks, I usually bring the dwarf multicannon and it's one of my favorite QoL tools. I love how it turns bloated, high‑spawn tasks into something surprisingly chill — you set it up, grab a snack, and watch groups melt. The big wins are clear: massive area damage, less clicking, and tons of uptime on multi‑spawn spots where monsters pile up. For tasks where the monsters cluster and respawn fast, the cannon basically doubles or triples my effective kill rate compared to single‑target methods. That said, it isn't a universal cure-all. There are places and assignments where the cannon is awkward, banned, or simply inefficient — cramped rooms, tiny caves, or situations where precision and tagging matter more than raw area damage. It also burns through cannonballs, so I keep an eye on cost vs. time saved. My rule of thumb: if a task is long, safe to cannon, and you want AFK or semi‑AFK efficiency, bring it. If you need high Slayer XP per hour or are after a picky rare drop, I sometimes switch to more controlled methods and enjoy the extra interaction and speed. In short: I use it a lot, but selectively — it's a tool, not a requirement, and I love the pace it gives me on the right tasks.

Lately I've been wearing the bonecrusher on almost every slayer grind and it made a surprisingly big difference in how smooth my trips feel. I find the biggest perk is the mental and inventory relief: bones get processed on the spot, which means I don't have to pause to bury them or carry space-heavy bone stacks that clutter my loots. For monsters that drop lots of low-value bones—skeletons, lesser demons, many slayer fodder—this saves tiny seconds that add up over hours. That means fewer bank trips, less clicking, and more continuous kills, which is exactly what you want if you're chasing efficient XP per hour. It's not flawless though. If you're planning to sell certain bones or use them for booming profit methods, the auto-burying can be annoying. Also for tasks where you want to pick up rare drops and prayer XP isn't worth sacrificing the occasional drop, you might toggle it off. Overall, for steady, relaxed slayer efficiency it's one of those quality-of-life items I never want to go without—keeps my trips cleaner and my focus on the kills, which I love.

Want to craft mist runes in 'Old School RuneScape' without touching quests? I got you — I used to poke at this exact problem and figured out a few clean routes that don't require quest locks. First off, mist runes are created through Runecrafting at the appropriate altar using pure or rune essence. If you don’t want to do quests, your best bet is to either go to the altar directly with a talisman or tiara for that elemental altar, or use a more general method like the Ourania (ZMI) altar which spits out mixed runes without needing a specific talisman. I personally like the ZMI route for lazy grind sessions because it removes the chore of switching altars and gives steady XP alongside the chance for mist runes. Practical tips I follow: bring lots of essence (buy from the Grand Exchange or mine it if you prefer), fill your inventory and pouches, and plan your banking/teleport route so each run is quick. If you want speed, learn a consistent route to the altar (Abyss runs are fast if you can access them) and stack your essence pouches every trip. It’s not the most glamorous method, but it’s reliable and keeps me crafting while I listen to playlists — nice, chill XP and rune profit at the same time.

If you’re knee-deep in Slayer tasks and trying to pick a reliable go-to piece of kit, the Amulet of Fury is one of those comfy constants I keep coming back to. I’ve worn it through a huge variety of tasks — everything from long, repetitive slayer chains to the odd risky bossish fight — and what I like most is how unspectacularly dependable it is. It doesn’t have a flashy special effect, but it gives strong, well-rounded combat bonuses that translate into consistent kills and fewer annoying trips to the bank to swap necklaces mid-task. Practically speaking, I treat Fury as my default melee amulet for general tasks. When I’m doing mixed or unpredictable assignments where I don’t want to fuss over maximizing a tiny DPS edge, the Fury keeps my offense and defense healthy. That reliability matters during long sessions: fewer mistakes, less swapping, and overall smoother XP-per-hour. That said, it’s not the best option for every single slayer creature. For undead-heavy tasks I’ll drop the Fury for the 'salve amulet' or its enhanced version, because those slayer-specific bonuses often beat Fury’s all-rounders. Likewise, if I’m doing highly specialized boss tasks, sometimes a pricier, purpose-built necklace will push kills per hour higher. I also think about risk and cost: the Fury is relatively pricey, so if I’m doing very dangerous tasks where deaths are plausible and I’m not rich, I’ll sometimes use a cheaper amulet to avoid a large loss on a skull. On the flip side, when profit or speed matters and death risk is low, wearing Fury is a straightforward DPS and survivability boost. My big piece of practical advice: pick your necklace to match the task — Fury is your dependable default, but swap it when a clear slayer-specific or boss-specific option exists. Overall, for the grindy, everyday slayer you’ll likely enjoy using Fury more than you expect, and it’s a comfy staple in my gear closet.

Quick heads-up: mist runes don't exist in 'Old School RuneScape', so there aren't any OSRS quests that unlock crafting for them. If you're trying to craft runes in OSRS the basic thing you need is the 'Rune Mysteries' quest, because that opens up the Runecrafting skill. After that you use rune essence or pure essence at the various altars (or the ZMI altar for faster XP) and meet the level requirements for each rune. Mist, mud, smoke and dust are part of later updates to 'RuneScape' (the modern version) and were not carried over into the nostalgic OSRS ruleset. I always tell newer players to lean on classic runes — air, water, earth, fire — and get comfortable with altars and pouches first; it saves a lot of headache. Feels weird that some cool elemental runes are missing, but it keeps OSRS close to its old-school vibe.

Hot take: mist runes can be profitable, but it's rarely a slam-dunk. I tend to eyeball a few things before deciding to sell anything on the Grand Exchange: current buy and sell prices, volume, and how I acquired the runes. If I made them myself or picked them up in bulk, even a tiny margin per rune can add up into decent gp over time. If I bought them hoping to flip, though, you need a clear spread between buy and sell prices and enough market activity to move your stacks. I usually check price graphs for a day or week to catch spikes or dips, then decide whether to list in one big chunk or split into smaller offers. Low-volume items can sit forever if you oversaturate the market. Another thing I consider is opportunity cost — could I convert those resources into something people actually want more right now? If not, selling runes slowly and watching the market is the safer play. Bottom line: profitable sometimes, frustrating other times. I sell when the numbers are clearly in my favor and I’m not emotionally attached to the inventory — keeps my bank healthier and my gameplay less stressful.

Okay, here's the straight talk: you need 90 Slayer to be assigned greater demons as a Slayer task in Old School RuneScape. I ran into this a while back when I was grinding mid-level monsters — greater demons felt like a weird gate because their combat level is higher than lots of people expect, but the real limiter for getting them on task is that 90 Slayer threshold. If you’re gearing up, treat them like a mid-to-high-level slayer trip: decent melee or ranged gear, prayer flicking or protection depending on where you’re fighting, and consider a cannon if you’ve got the money and a safe multi-spot. Slayer masters won’t give you greater demons below 90, but you can still kill them outside of a task for drops; you just won’t get Slayer XP from those kills. I found it a satisfying step-up in difficulty when I hit the requirement — good challenge and decent drops, so bring your best setup and enjoy the grind.

I love talking gear, so here's my long-winded, gear nerd take for crushing 'Old School RuneScape' dust devil slayer tasks. If you lean melee, my go-to is a slayer-friendly, high-DPS setup: 'Slayer helm (i)' for the boost, a reliable mainhand like an abyssal whip (or dragon scimitar if you prefer special attacks), and a Dragon defender in the shield slot for pure offense. Top it with Barrows gloves, an Amulet of fury (or a combat ammy you’ve got), Bandos or Neitiznot-style platebody/legs depending on what you own, Dragon boots, and a Fire cape or similar damage cape. Ring slot? Berserker ring (imbued) if you can; if not, a strength ring will do. Inventory wise bring super combat potions (or attack/strength mixes), a few prayer potions if you use piety/overloads, and food — sharks or manta rays for consistency. If you want to cut costs, swap the top-end pieces for Proselyte/Yak-hide alternatives and skip the imbues. I usually alternate between budget runs and my nice set; both clear fast, and the task becomes chill rather than a grind. Feels good to watch the kills pile up with minimal downtime.
