B2B Slayer Task OSRS Guide for Maximum Efficiency and Profit
In Old School RuneScape (OSRS), the term “B2B” or “back-to-back” Slayer tasks refers to receiving the same Slayer task consecutively from a Slayer Master, a rare but highly desirable occurrence for players aiming to maximize efficiency, experience (XP), or gold (GP). This blog post dives into the mechanics, strategies, and benefits of B2B Slayer tasks, offering tips to increase your chances of getting them and make the most out of these opportunities. Whether you’re a mid-level player or a seasoned slayer, this guide will help you optimize your Slayer grind.
B2B Slayer tasks occur when a player completes a Slayer task and receives the same task again immediately from the same Slayer Master. This phenomenon is exciting because it allows players to stay in the same location, use the same gear, and maintain momentum without needing to switch setups or travel across Gielinor. However, B2B tasks are largely luck-based due to the task weighting system used by Slayer Masters.
How Task Weighting Affects B2B Chances
Each Slayer Master assigns tasks based on a weighting system, where tasks with higher weights are more likely to be assigned. For example, Duradel’s most common task might be Abyssal Demons (weight 12), while less common tasks like Iron Dragons (weight 7) are rarer. The chance of a B2B task depends on the task’s weight relative to the total weight of all available tasks. You can calculate the probability using the formula: (Task Weight / Total Weight) × 100%. For instance, if Abyssal Demons have a weight of 12 and the total weight is 200, there’s a 6% chance of getting them again.
Why B2B Tasks Are Valuable
B2B tasks save time and resources, especially for high-XP or high-GP tasks like Gargoyles or Kurasks. They’re particularly beneficial for:
- Efficiency: No need to change gear or travel to a new location.
- Profit: Repeated high-value tasks can stack loot quickly.
- XP Gains: Staying on burstable or cannonable tasks boosts XP rates.
- Milestone Bonuses: Completing multiple tasks in a row can hit milestone rewards (e.g., every 10th, 50th, or 100th task) faster.
Top Slayer Tasks for B2B Opportunities
Not all tasks are worth hoping for in a B2B scenario. Below, we highlight some of the best tasks to aim for, focusing on profitability and XP efficiency. These tasks are ideal for players with mid-to-high Slayer levels (70+).
Gargoyles (Level 75 Slayer)
Gargoyles, found in the Slayer Tower, are a fan favorite for their consistent loot, including Rune items and alchables. They yield 600,000–800,000 GP per hour and decent XP when using a cannon. Their task weight makes them moderately common with higher-level Slayer Masters like Duradel.
Kurasks (Level 70 Slayer)
Kurasks offer around 400,000–600,000 GP per hour with noted drops like Limpwurt Roots and White Berries. They require Leaf-Bladed weapons or Broad Bolts, making them accessible for mid-level players. Their multi-combat area in the Fremennik Slayer Dungeon allows for cannon use, boosting efficiency.
Skeletal Wyverns (Level 72 Slayer)
Skeletal Wyverns are among the best for GP, offering up to 700,000 GP per hour with Melee or 400,000 with Ranged. Extending this task is highly recommended due to their valuable drop table, including Wyvern Bones and Granite items.
Smoke Devils (Level 93 Slayer)
Smoke Devils in the Smoke Devil Dungeon are ideal for burst or barrage setups, providing up to 150,000 Slayer XP per hour in multi-combat zones. They’re also profitable, with drops like Runes and Herbs, making them a prime B2B target for high-level players.
Strategies to Increase B2B Task Chances
While B2B tasks are random, you can tilt the odds in your favor by optimizing your task list and Slayer setup. Here are actionable strategies to improve your chances.
Optimize Your Block and Skip List
Blocking low-weight, unprofitable, or slow tasks reduces the total task weight, increasing the likelihood of getting high-weight tasks repeatedly. For example, blocking Black Demons or Hellhounds (if not bossing) with Duradel can make tasks like Abyssal Demons or Gargoyles more frequent. Use Slayer points to skip undesirable tasks that don’t align with your goals. A suggested block list for Duradel includes:
- Black Demons: Low profit unless bossing.
- Hellhounds: Slow XP unless targeting Cerberus.
- Waterfiends: Poor drops and XP.
- Iron Dragons: Time-consuming for low reward.

Use the Right Slayer Master
Choose a Slayer Master based on your combat and Slayer level. Duradel (Level 100 Slayer, 50 Combat) is best for high-level players due to his high-weight, profitable tasks. Nieve/Steve (Level 85 Slayer) is great for mid-level players, though their task list includes more low-XP tasks like Fire Giants. For B2B tasks, stick to one master to maintain consistent task weighting. Switching between masters (e.g., Duradel and Turael) disrupts the streak.
Extend High-Value Tasks
Using Slayer points to extend tasks like Dust Devils, Nechryaels, or Skeletal Wyverns increases the number of monsters per task (e.g., adding ~100 kills). This not only boosts XP and GP but also gives you more chances to roll the same task again upon completion. Pair this with a Bracelet of Slaughter to extend task length by 20% for cannonable or burstable tasks.
Maximizing Efficiency During B2B Tasks
When you luck out with a B2B task, make sure you’re set up to capitalize on it. Here’s how to optimize your setup and approach.
Gear and Inventory Setup
Your gear depends on the task, but general recommendations include:
| Task | Recommended Gear | Inventory |
|---|---|---|
| Gargoyles | Slayer Helmet (i), Bandos Armor, Dragon Scimitar | Prayer Potions, Super Restores, High Alch Runes |
| Kurasks | Leaf-Bladed Battleaxe, Proselyte Armor | Herb Sack, Seed Box, Cannonballs |
| Smoke Devils | Trident of the Seas, Occult Necklace | Blood Barrage Runes, Prayer Potions |
| Skeletal Wyverns | Dragonfire Shield, Armadyl Crossbow | Antifire Potions, Food (Sharks) |
Always wear a Slayer Helmet (i) for its 16.67% damage and accuracy boost on task. Imbue it via Nightmare Zone for even better stats.
Use Cannons and Burst Spells
For multi-combat tasks like Smoke Devils or Dagannoths, use a Dwarf Multicannon to speed up kills and boost XP. For magic-based tasks, Ice Barrage or Blood Barrage in multi-combat areas (e.g., Catacombs of Kourend) can yield massive XP rates. Ensure you have enough cannonballs and runes, as these methods are costly but efficient.
Loot Management
High-value tasks generate a lot of loot, so use tools like the Herb Sack, Seed Box, or Looting Bag to maximize inventory space. For alchable drops (e.g., Rune items from Gargoyles), bring Fire Runes and a Staff of Fire to High Alch on the spot, reducing bank trips.
Community Insights and B2B Records
The OSRS community loves sharing B2B streaks, especially on platforms like Reddit. One player reported a “B2B2B2B” streak (four consecutive tasks) at Revenants, highlighting the thrill of extended runs. While such streaks are rare, they’re a testament to the potential of optimized task management. Join communities like the 2007Scape Reddit or OSRS Discord to share your B2B experiences and learn from others.
Tips from Veteran Players
Veteran slayers recommend:
- Prayer Bonus Gear: Use Proselyte Armor for tasks like Kurasks to sustain Prayer with fewer potions.
- Slayer Cape Perk: At 99 Slayer, the Slayer Cape offers a chance to teleport to a task location, saving time during B2B streaks.
- Task Storage: Unlock the ability to store rare tasks (e.g., Corporeal Beast) to preserve them for later, especially if you’re mid-streak.
