OSRS Best Tasks to Extend for Maximum Efficiency and Rewards

OSRS Best Tasks to Extend for Maximum Efficiency and Rewards


In Old School RuneScape (OSRS), the Slayer skill offers a thrilling way to train combat while earning unique rewards. One key strategy to optimize your Slayer experience is extending specific tasks. Extending a task increases the number of monsters you need to kill, allowing you to maximize experience, loot, and efficiency without frequent trips to your Slayer master. But not all tasks are worth extending—some shine brighter than others due to their rewards, ease, or synergy with your goals. This guide dives into the best Slayer tasks to extend in OSRS, helping you make informed choices to boost your gameplay.

Extending a Slayer task means using Slayer reward points to increase the assigned monster count, typically by 10-20% or more, depending on the task. This mechanic, unlocked via the “Bigger and Badder” reward or specific task extensions, reduces the need to return to your Slayer master, saving time and letting you focus on combat and loot. However, extending every task isn’t practical—points are limited, and some tasks are too slow or unrewarding. Choosing the right tasks to extend can:

  • Boost XP rates by focusing on high-XP monsters.
  • Increase profit through valuable drops.
  • Streamline training by minimizing downtime.

Let’s explore the top tasks worth extending, balancing experience, profit, and efficiency.

Best Slayer Tasks to Extend for Experience

If your goal is to level up Slayer or combat skills quickly, extending tasks with high XP rates is key. These tasks often involve monsters that are quick to kill or offer substantial experience per kill.

Dust Devils

Dust Devils, found in the Smoke Dungeon or Catacombs of Kourend, are a fantastic task to extend. With a Slayer level requirement of 65, they’re accessible to mid-level players and offer excellent combat XP due to their low defense and high hitpoints. Using a Dwarven Multicannon in the Catacombs can push your XP rates to 40-50k per hour.

  • Why extend? Fast kills, decent loot (e.g., Dragon Chainbody, alchables), and multi-combat areas for cannon use.
  • Tip: Wear a Facemask or Slayer Helmet to avoid stat drain from smoke.

Nechryaels

Nechryaels, requiring 80 Slayer, are another XP powerhouse. Located in the Slayer Tower or Catacombs, they summon Death Spawns, which can slow kills if not handled efficiently. However, with area-of-effect attacks like Chinchompas or Burst spells, you can clear them quickly, netting 50-60k XP per hour.

  • Why extend? High XP per kill and valuable drops like Rune Boots and alchables.
  • Tip: Use the Catacombs for a chance at Totem pieces and better loot.

Greater Demons

Greater Demons (Slayer level 1, but often assigned at higher levels) are a solid choice for XP-focused players. Found in places like the Chasm of Fire or Catacombs, they’re easy to kill with high hitpoints and low defense, offering steady XP gains.

  • Why extend? Simple mechanics, cannon-friendly, and occasional high-value drops like Clue Scrolls.
  • Tip: Use Protect from Melee to minimize damage in multi-combat areas.

Top Tasks to Extend for Profit

For players chasing gold, extending tasks with lucrative drops can significantly boost your bank. These tasks often involve monsters with rare, high-value items or consistent loot tables.

Gargoyles

Gargoyles, requiring 75 Slayer, are a goldmine when extended. Found in the Slayer Tower, they drop Granite Mauls, Clue Scrolls, and alchables, averaging 200-300k GP per task. Their relatively low combat stats make them easy to farm with a decent setup.

  • Why extend? Consistent profit and a chance at rare drops like the Granite Maul (worth ~150k).
  • Tip: Bring a Rock Hammer to finish them off and speed up kills.

Kurasks

Kurasks (Slayer level 70) are a niche but profitable task. Located in the Fremennik Slayer Dungeon, they drop valuable items like Leaf-Bladed weapons, Mystic Robes, and herbs. Their high defense requires specific weapons (Leaf-Bladed or Magic), but the loot makes it worthwhile.

  • Why extend? High-value drops with low competition for spots.
  • Tip: Use a Leaf-Bladed Battleaxe or Broad Bolts for efficient kills.

Abyssal Demons

Abyssal Demons (Slayer level 85) are a fan favorite for profit. Found in the Slayer Tower or Catacombs, they drop the coveted Abyssal Whip (~1/512 chance) and Abyssal Dagger, alongside consistent alchables and Clue Scrolls.

  • Why extend? Chance at million-GP drops and steady income from smaller loot.
  • Tip: Use Arclight for faster kills if you have Darklight charges.

Tasks to Extend for Unique Rewards

Some tasks are worth extending not just for XP or gold but for their unique drops, which can unlock new content or enhance your account.

Basilisks

Basilisks (Slayer level 40) in the Fremennik Slayer Dungeon drop the Basilisk Jaw, a rare component for the Neitiznot Faceguard. While the jaw is a 1/1,000 drop, extending this task increases your chances of snagging it.

  • Why extend? Access to one of the best melee helmets in the game.
  • Tip: Wear a Mirror Shield to avoid stat-draining attacks.

Demonic Gorillas

Demonic Gorillas, assigned as Black Demons (Slayer level 1, but high combat recommended), are a post-quest task after Monkey Madness II. They drop Zenyte Shards and Ballista components, which are worth millions.

  • Why extend? Rare drops for end-game jewelry and weapons.
  • Tip: Learn their attack switches (melee, ranged, magic) to minimize damage.

Strategic Considerations for Extending Tasks

Before spending your hard-earned Slayer points, consider these factors to ensure you’re extending the right tasks for your playstyle and goals.

Slayer Point Costs

Extending a task typically costs 100-250 Slayer points, depending on the monster. Ensure you have enough points to maintain other unlocks, like Superior Slayer Encounters or the Slayer Helmet. Prioritize tasks that align with your current level and gear.

Location and Gear Efficiency

Choose tasks with accessible locations and minimal gear requirements. For example, Catacombs tasks like Dust Devils or Nechryaels benefit from cannon setups and Totem drops, making them more rewarding when extended.

Task Synergy with Goals

Align extensions with your account’s objectives. If you’re chasing 99 Slayer, focus on XP-heavy tasks like Nechryaels. If you need cash, prioritize Gargoyles or Abyssal Demons. For unique items, Basilisks or Demonic Gorillas are ideal.

Task Slayer Level Why Extend? Key Drops Recommended Gear
Dust Devils 65 High XP, cannon-friendly Dragon Chainbody, alchables Slayer Helmet, cannon
Gargoyles 75 Consistent profit Granite Maul, Clue Scrolls Rock Hammer, melee gear
Abyssal Demons 85 Rare high-value drops Abyssal Whip, Dagger Arclight, Slayer Helmet
Basilisks 40 Unique helmet component Basilisk Jaw Mirror Shield, melee gear
Demonic Gorillas 1 (post-quest) End-game item drops Zenyte Shard, Ballista parts Tribrid gear, prayer potions

Extending Slayer tasks in OSRS is a game-changer for efficiency, whether you’re grinding XP, chasing profit, or hunting unique rewards. By focusing on tasks like Dust Devils, Gargoyles, Abyssal Demons, Basilisks, and Demonic Gorillas, you can tailor your Slayer journey to your goals. Use your points wisely, match tasks to your gear and level, and watch your rewards stack up. Which task will you extend first?
