OSRS Best Tasks to Extend for Maximum Efficiency and Rewards

OSRS Best Tasks to Extend for Maximum Efficiency and Rewards


Old School RuneScape (OSRS) offers a rich slayer system that keeps players engaged with its variety of tasks and rewards. One of the best ways to optimize your slayer experience is by extending certain tasks. Extending tasks means increasing the number of monsters you’re assigned to kill, allowing you to maximize experience, loot, and efficiency. But not all tasks are worth extending. In this guide, we’ll explore the best tasks to extend in OSRS, why they’re worth it, and how to make the most of your slayer points. Whether you’re a seasoned slayer or just starting out, this SEO-friendly guide will help you level up smarter.

Extending a slayer task costs 100 slayer points and increases the assigned monster count by a significant amount—usually 50% to 100% more, depending on the task. This mechanic is a game-changer for players looking to grind efficiently. By extending the right tasks, you can earn more XP per hour, gather valuable drops, and reduce the frequency of returning to your slayer master. However, choosing the wrong tasks to extend can waste points and time. Let’s dive into the criteria that make a task worth extending.

Criteria for Choosing Tasks to Extend

Not every slayer task is a good candidate for extension. Here’s what to consider:

  • Experience Rates: Tasks with high XP potential are prime candidates.
  • Loot Value: Monsters with profitable drops can offset the cost of extending.
  • Kill Speed: Fast-to-kill monsters make extended tasks less tedious.
  • Location Efficiency: Tasks in multi-combat areas or with cannon potential are ideal.

Benefits of Extending Tasks

Extending tasks offers several advantages:

  • More XP per Assignment: Longer tasks mean more kills and more experience.
  • Better Loot Hauls: Increased monster counts boost your chances of rare drops.
  • Fewer Trips to Slayer Masters: Spend less time traveling and more time slaying.

How to Extend Tasks in OSRS

Extending tasks is straightforward, but it requires some preparation. Here’s a step-by-step guide to get you started.

Unlocking the Extend Option

To extend tasks, you need to unlock the ability through the Slayer reward shop. Here’s how:

  1. Visit a Slayer master (e.g., Duradel in Shilo Village).
  2. Open the rewards interface.
  3. Spend 100 slayer points to unlock the “Bigger and Badder” perk (optional for some tasks) or directly extend a task.

Managing Slayer Points

Slayer points are precious, so use them wisely:

  • Earn Points: Complete tasks consecutively for streaks (e.g., 10th task = 50 points, 50th = 250 points).
  • Prioritize: Only extend tasks that align with your goals—XP, profit, or both.
  • Skip Bad Tasks: Use points to skip unprofitable or slow tasks instead of extending them.
