The Best AFK Combat Training Spots in OSRS (2026)

Nobody has ever enjoyed clicking a rock crab every four seconds for six hours. The entire point of AFK combat training is that your XP keeps ticking while you cook dinner, answer emails, or lose an evening to YouTube on the second monitor.

The problem is that “AFK” covers everything from “glance over every ten minutes” to “click once, come back to a logout screen”, and most lists pretend those are the same thing.

I’ve trained several accounts through all three spots below, including one ill-advised ironman. Here’s how they actually stack up in 2026.

The two timers that decide everything

First, aggression. Crabs and their cousins attack you automatically when you enter their patch, but after roughly 10 minutes they get bored and stop. The fix is to jog a couple dozen tiles out of the area and walk back, at which point every crab remembers it hates you and the cycle restarts. That 10-minute window is your real AFK budget at any crab spot.

Second, the idle logout timer. Stop interacting with the client for long enough and the game logs you out, XP waterfall or not. In practice this means checking in every 10 to 20 minutes depending on method. Anyone selling you a “fully AFK overnight” method is describing a bannable macro, not a training spot.

A quality-of-life note before we start: if you use RuneLite, turn on the Idle Notifier plugin. It pings you the moment the crabs stop attacking or your character stands around doing nothing, which turns “check the screen every few minutes out of paranoia” into “wait for the ping”. It’s the single biggest upgrade to AFK training and it costs nothing.

And a third thing that isn’t a timer but matters more than people admit: world population. Crab spots are first-come, first-served.

Hop two or three worlds before settling, because an empty double-spawn on a dead world beats squabbling over a triple-spawn on world 302 every single time.

The quick comparison

The ranges are wide because stats and gear matter enormously. A level 60 account swinging a rune scimitar lives at the bottom of each range. A 90+ account with a whip, piety and a stack of combat potions lives at the top.

Sand Crabs: the zero-requirement classic

Sand Crabs sit on the Hosidius coastline in Zeah, and they’re the reason Rock Crabs in Rellekka have been a ghost town for years.

The stats tell you why anyone can use them: 60 hitpoints, 1 Defence, and a max hit of 1. You could AFK these things in a party hat and nothing else.

The routine: find a tile where two or three spawns overlap, flick on auto-retaliate, and let them queue up to bounce off you. When the aggression runs out, jog down the beach past the farmhouse and walk back.

If the good spots are taken, and on busy worlds they will be, Crabclaw Isle costs 10,000 gp per entry and is nearly always deserted. Cheap rent for a private beach.

Gear priority is pure strength bonus, since defence is wasted on monsters that cannot hurt you. Rune scimitar at 40 Attack, dragon scimitar at 60 after Monkey Madness, whip at 70. Each step is worth roughly 5 to 10k XP an hour on its own.

Potions help if you’re optimising, and are completely optional if you’re not. Both approaches are valid, which is rather the charm of the place.

Expect 20 to 30k XP/hr through the level 50 to 70 range and 40 to 50k/hr once your melees pass 90. Modest numbers, but no other spot in the game asks for zero quests, zero stats and zero supplies.

The overlap tiles, spawn mechanics and the quickest reset route are all mapped out in this sand crabs training guide, worth ten minutes of reading before you donate a weekend to the beach. Raw monster stats live on the Sand Crab wiki page.

Ammonite Crabs: the same bicycle with a motor

Ammonite Crabs on Fossil Island are Sand Crabs after a trip to the gym. 100 hitpoints instead of 60, still 1 Defence, still hitting like a damp sponge, still on the 10-minute aggression cycle. Two-thirds more XP per kill for identical effort.

The toll booth is Bone Voyage, which needs 100 Kudos from the Varrock Museum, which in turn means The Dig Site quest and some fossil cleaning.

Budget a few hours. Those hours repay themselves within a day of training: 30 to 40k XP/hr at mid stats, 50 to 60k/hr at high stats, consistently 20 to 30 percent ahead of Sand Crabs.

Best tiles are on the northern beach where up to four spawns reach you at once; stats and locations are on the Ammonite Crab wiki page. A bonus nobody mentions: the quest wall filters out half the competition, so Fossil Island worlds stay quiet in a way Hosidius never does.

Nightmare Zone: the AFK ceiling

NMZ is a minigame in Yanille where you fight dream versions of bosses you’ve already beaten in quests, and with the right setup it’s the longest you can legitimately ignore this game while gaining combat XP. Up to 20 minutes between clicks.

The setup sounds unhinged the first time you hear it. Start a customisable rumble with only weak melee bosses selected. Drink absorption potions, bought with NMZ points, to bank up to 1,000 damage of protection. Then eat a dwarven rock cake until you sit at exactly 1 hitpoint.

Every boss hit now drains absorption instead of hurting you, and if you’re wearing full Dharok’s, being at 1 HP means you hit like a truck for the entire dream.

Overloads stack on top. Realistic rates run 70 to 90k XP/hr, and Dharok’s with overloads clears 100k. I haven’t retested my Dharok’s rates since the last combat balance patch, but the method itself hasn’t moved in years.

The entry fee is your quest log: at least five completed quests from the eligible list. Vampyre Slayer, Fight Arena, Tree Gnome Village, The Grand Tree and Lost City are the classic budget five.

Your first sessions go on earning points for potions rather than XP, and a Dharok’s set is not pocket change for a newer account. Theoatrix’s NMZ setup video covers the point maths, and boss picks better than text ever will.

One honest downside: NMZ pays you nothing. No drops worth keeping, pure XP. The crabs at least let the bones and occasional seaweed pile up while you ignore them.

Honourable mentions, briefly

Rock Crabs still exist and are still worse: 50 HP and thin spawns. Kharidian desert bandits are the odd one out, permanently aggressive if you wear a Saradomin or Zamorak item, so no reset jogging at all.

Tempting for high-level accounts, but they hit hard enough to demand real food, and a method that eats your bank while you’re not looking has missed the point of this article.

Pick for your next ten hours, not for max

If your account is fresh, walk to Hosidius tonight and start. If you can stomach the Varrock Museum, knock out Bone Voyage this week and never think about Sand Crabs again.

If your quest log already covers five NMZ bosses, spend one evening on points and your melee grind is solved until 99. And whichever you choose, do the world hop first. Ten seconds of hopping buys more XP than any amount of reading about it.
