Best Post-Max Slayer Block List for OSRS: Optimize Your XP and GP in 2025

Training Slayer in Old School RuneScape (OSRS) after hitting level 99 or max combat stats is a different beast. You’re no longer just grinding for levels—you’re chasing efficiency, profit, or both. A well-crafted Slayer block list is your key to skipping the slog and focusing on tasks that align with your goals. This guide dives into the best post-max Slayer block list for 2025, tailored for players with maxed combat stats (99 Attack, Strength, Defence, Ranged, Magic, and Hitpoints) and high Slayer levels. Whether you’re after max XP per hour, gold, or a balance of both, we’ll break down the tasks to block, skip, and prioritize, ensuring you get the most out of every assignment.

Once you’ve maxed your combat stats, Slayer becomes less about leveling and more about optimization. Blocking undesirable tasks allows you to avoid time-wasting or low-reward assignments, streamlining your task rotation for better XP, loot, or both. Each block slot (up to seven with 300+ quest points and the Elite Lumbridge & Draynor Diary) costs 100 Slayer reward points, so choosing wisely is crucial. A good block list saves time, boosts efficiency, and keeps your Slayer point reserves healthy for skips or unlocks.

Understanding Task Weightings

Slayer Masters assign tasks based on weightings—higher-weighted tasks are assigned more often. Blocking high-weighted, low-value tasks maximizes your chances of getting desirable ones. For post-max players, Duradel and Morvran are the go-to Slayer Masters due to their high-level task pools, but their lists include some duds you’ll want to block.

Balancing XP vs. Profit

Post-max Slayer goals vary. Some players prioritize XP for prestige or 200M goals, while others chase profit from high-value drops like those from Hydra or Cerberus. Your block list should reflect your focus—XP-heavy tasks like Dust Devils or Nechryaels for burst setups, or profitable ones like Abyssal Demons for whip drops. We’ll cover lists for both approaches.

Best Slayer Block List for XP Efficiency

For players aiming to maximize Slayer XP per hour, the goal is to block tasks that are slow, can’t be barraged or cannoned effectively, or offer mediocre XP despite decent loot. With maxed combat stats, you have access to top-tier gear like the Scythe of Vitur, Inquisitor’s Mace, or Dragon Hunter Crossbow, making multi-combat burst tasks or cannonable assignments the fastest. Here’s a block list optimized for XP with Duradel or Morvran:

Top Tasks to Block for XP

• Greater Demons: High weighting (9 for Duradel), but slow without a cannon or burst setup. Even with maxed stats, they’re outclassed by tasks like Nechryaels.
• Black Demons: Weighted at 8, these are tedious without a barrage setup. Demonic Gorillas (requires Monkey Madness II) are a better alternative for profit or XP.
• Hellhounds: Also weighted at 8, they’re decent for clue hunters but terrible for XP unless you’re killing Cerberus (91 Slayer). Block unless you’re bossing.
• Fire Giants: Weighted at 7, they’re too spread out for efficient cannoning and offer low XP compared to burstable tasks.
• Drakes: Weighted at 6, slow to kill even with maxed Ranged or Melee, and their loot doesn’t justify the time.
• Wyrms: Similar to Drakes, weighted at 6, with poor XP rates and lackluster drops unless you’re after rare bones.
• Iron/Steel Dragons: Weighted at 5, these are painfully slow without a Dragon Hunter Lance or Crossbow, and their XP rates don’t compete with top tasks.

Why These Blocks Work

This list targets high-weighted tasks that clog up your assignment pool. By blocking them, you increase the odds of getting XP-heavy tasks like:

• Dust Devils: Burstable in the Catacombs of Kourend for 100k+ XP/hour with Ice Barrage.
• Nechryaels: Also burstable, offering 90-110k XP/hour and decent loot like Rune Boots.
• Barragable Trolls: Fast XP with a cannon in multi-combat areas like the Keldagrim entrance.

With seven slots, you cover the worst offenders, leaving room for tasks you can complete quickly with maxed gear.

Best Slayer Block List for Profit

If your goal is gold, you’ll want to block tasks with poor loot while keeping profitable ones like Abyssal Demons, Gargoyles, or boss tasks (e.g., Hydra, Cerberus). Konar quo Maten is a strong choice for profit due to Brimstone Keys (average 89k loot per key), but Duradel works too if you prefer a broader task pool. Here’s a profit-focused block list:

Tasks to Block for Maximum GP

• Suqah: Weighted at 8 for Duradel, they’re slow to kill without a cannon and drop nothing valuable.
• Bloodveld: Weighted at 8, their loot is underwhelming compared to Mutated Bloodvelds in the Catacombs.
• Ankou: Weighted at 7, decent XP but their drops (e.g., Rune items) pale compared to boss tasks.
• Fire Giants: As mentioned, low-value drops and slow XP make them a prime block candidate.
• Drakes: Poor loot and slow kills, even with maxed gear.
• Wyrms: Similarly bad drops and XP, not worth the time.
• Greater Demons: Low-value drops unless you’re killing K’ril Tsutsaroth, which is better as a boss task.

Profit-Oriented Task Prioritization

Blocking these opens up assignments like:

• Abyssal Demons: High-value drops like the Abyssal Whip (~1.4M).
• Gargoyles: Consistent profit from Granite Mauls and gems, plus decent XP.
• Hydra: Requires 95 Slayer, but Alchemical Hydra drops are worth millions (e.g., Dragon Claws, Hydra Leather).

Konar’s location-specific tasks add Brimstone Keys, boosting profit further, especially on tasks like Abyssal Demons in the Slayer Tower.

Hybrid Block List for XP and Profit

Many post-max players want a mix of XP and GP without committing fully to one. A hybrid block list balances tasks that offer solid XP with those that drop valuable loot. Here’s a versatile list for Duradel or Morvran:

Task to Block	Weighting (Duradel)	Reason
Greater Demons	9	Slow without burst setups; poor drops unless bossing.
Black Demons	8	Tedious without barrage; Demonic Gorillas are better.
Hellhounds	8	Low XP and loot unless killing Cerberus.
Suqah	8	Slow kills, no cannon, and negligible drops.
Drakes	6	Poor XP and loot for maxed players.
Wyrms	6	Similar to Drakes, not worth the time.
Iron/Steel Dragons	5	Too slow without specialized gear; low XP.

Tasks to Keep and Extend

With this list, you’re likely to get:

• Dust Devils/Nechryaels: Extend these for 100k+ XP/hour with barrage setups.
• Abyssal Demons: Keep for whip drops and solid XP.
• Kuradal’s Dungeon Tasks: Like Gargoyles or Hellhounds, which offer ferocious rings and decent loot.

Use Bracelets of Slaughter to extend high-XP tasks and Expeditious Bracelets to rush through mediocre ones.

Tips for Managing Your Block List

Even with the perfect block list, Slayer efficiency depends on smart management. Here are actionable tips to keep your post-max Slayer grind smooth:

Maintain Slayer Points

Blocking costs 100 points, and skipping costs 30. To avoid running dry, use Turael for nine quick tasks, then hit Konar or Duradel for the 10th to cash in bonus points (up to 250 for the 50th task). This “Turael boosting” keeps your reserves high.

Use Toggleable Tasks as Pseudo-Blocks

Tasks like Fossil Island Wyverns or Red Dragons can be toggled off without spending points. Check your Slayer reward shop and disable any you don’t want—it’s like a free block.

Adjust Based on Gear and Playstyle

Your block list isn’t set in stone. If you lack a Scythe or Barrage runes, tasks like Trolls might be too slow, so consider blocking them temporarily. Swap blocks as your gear or goals change—maybe unblock Hellhounds if you’re chasing Cerberus Primordial Crystals.

Skip Strategically

Low-weighted tasks like Waterfiends (weight 2) are better skipped than blocked to save slots for high-weighted duds. Keep 100-200 points on hand for skipping to maintain flexibility.

With maxed combat stats, you have the power to crush any Slayer task, but not every task is worth your time. This 2025 post-max Slayer block list—whether for XP, profit, or a hybrid approach—helps you focus on what matters. Block smart, skip strategically, and watch your efficiency soar.
