OSRS Slayer Guide: 15 Tasks That Generate Massive Profit
If you’ve ever wondered which Slayer tasks are actually worth your time in Old School RuneScape, this guide cuts straight to the point. Not every task is a goldmine, and Slayer isn’t pure profit every hour of the grind. Cannonballs, potions, food, and high-end gear all chip away at your earnings. The real secret is understanding net profit, not just flashy drop values. Slayer rewards patience—sometimes, a steady income adds up slowly, and other times one rare, unique drop completely changes your bank value overnight.
With that in mind, here are some of the most profitable Slayer tasks in OSRS, ranging from relaxed AFK methods to high-risk, high-reward bossing.
Vyrewatch Sentinels (38 Slayer)
Vyrewatch Sentinels are one of the most AFK-friendly money makers in the game. They require 38 Slayer, but you must complete Sins of the Father to access them in Darkmeyer. With prayer bonus gear and access to an altar nearby, you can camp these almost indefinitely.
The big payoff is the Blood Shard, which drops at roughly 1 in 1,500. RNG can be brutal here, but that’s Slayer life. You might go dry—or you might get lucky and cash out early.
Gargoyles (75 Slayer)
A classic Slayer Tower staple, Gargoyles remain a consistent and reliable source of income. Each kill averages around 3,500 GP, translating to roughly 350k cheap Runescape gold per hour before uniques.
The Granite Maul drops at 1 in 256 and adds occasional spikes of profit. Investing 120 Slayer points into the Gargoyle Smasher perk is absolutely worth it, removing the need to manually finish kills with a rock hammer.
Brutal Black Dragons (77 Slayer)
Brutal Black Dragons are absurdly profitable for how relaxed they are. Each kill is worth around 30,000 GP, and with consistent kills, you can exceed 1.5 million GP per hour.
They drop dragon platelegs, dragon skirts, rune items, dragon bones, and black dragonhide every kill. With a bank and altar nearby, downtime is minimal, making this one of the most consistent money printers in Slayer.
Cerberus (91 Slayer)
Cerberus transforms Hellhound tasks into serious profit. At drop rate, you’re looking at about 3.7 million GP per hour. The catch? Regular drops are mediocre, and the real money comes from crystal uniques—especially the Primordial Crystal.
XP rates sit around 30k Slayer XP per hour, so even if RNG isn’t kind, you’re still progressing efficiently.
Tormented Demons (Greater Demon Tasks)
Tormented Demons don’t require a specific Slayer level—just completion of While Guthix Sleeps. With strong efficiency, they can bring in around 3.5 million GP per hour and nearly 60k Slayer XP per hour, which is exceptional for Greater Demons.
The Tormented Synapse, valued at tens of millions, drives profitability. While prices have settled over time, these are still extremely strong tasks.
Abyssal Sire (85 Slayer)
Following recent buffs, Abyssal Sire is both more profitable and better XP than before. Expect 3 million GP per hour and around 20–25k Slayer XP.
Uniques include abyssal daggers, bludgeon pieces, and whips. If you prefer something more relaxed, regular Abyssal Demons still offer whip drops at 1 in 512, with profits ranging from 100k to 750k GP per hour depending on luck.
Wilderness Slayer & Revenants
Wilderness Slayer raises the stakes—and the rewards. Revenants require no Slayer level when assigned by Krystilia and can generate 4 million GP per hour when killing efficiently.
Unlike many bosses, Revenants are valuable even without uniques. That said, PKers are everywhere, so deaths must be factored into your profit calculations.
Venenatis and Spindel (Spider Tasks)
These Wilderness bosses are extremely profitable, pulling in up to 5.5 million GP per hour at drop rate. The Voidwaker gem alone is worth over 20 million GP.
Survivability is the main challenge here. Teams, anti-PK gear, or strong escape mechanics are essential to protect your earnings.
Alchemical Hydra (95 Slayer)
Hydra remains one of the best Slayer bosses in the game. With solid gear and stats, you can expect around 4.5 million GP per hour.
The Hydra’s Claw is the big-ticket drop, but what makes Hydra special is its consistent regular loot. It’s also fantastic for Ironman progression and alchemy-based income.
Demonic Gorillas (Black Demon Tasks)
Demonic Gorillas are slower XP than cannoning regular Black Demons, but the profit potential is far higher. If money is the goal, this task is worth the tradeoff.
Vorkath (Blue Dragon Tasks)
With Dragon Slayer II completed, Blue Dragon tasks at Vorkath are incredibly lucrative. Using a Dragon Hunter Lance, profits can reach 4 million GP per hour.
While Vorkath’s uniques matter, much of the profit comes from consistent drops and dragon bones, making it one of the most stable money makers in OSRS.
Dagannoth Kings (Dagannoth Tasks)
Completing Dagannoth tasks at DKs can yield up to 2.8 million GP per hour with Fremennik Elite Diaries. Without them, profit drops to about 1.9 million RuneScape gold.
Even lower-level players can profit by safespotting Rex, who drops the Berserker Ring, still one of the most valuable DK uniques.
Araxxor (92 Slayer)
Currently, the most profitable Slayer task in the game, Araxxor, brings in over 6 million GP per hour. With a lower Slayer requirement than Hydra and excellent unique drops, it’s a top-tier choice for both mains and Ironmen.
Final Thoughts
Slayer becomes truly powerful when you combine smart task selection with patience. One lucky drop can outweigh dozens of average tasks, and many players have built massive banks—sometimes approaching a billion GP—just by prioritizing profitable Slayer assignments.
Whether you prefer AFK consistency or high-intensity bossing, OSRS Slayer offers a money-making path for every playstyle.
