Best Slayer Upgrades in OSRS: Boost Your Efficiency in 2025

If you’re grinding Slayer in Old School RuneScape (OSRS), you know it’s one of the most rewarding yet time-intensive skills. Whether you’re chasing level 99, hunting for profit, or just enjoying the combat, the right upgrades can make all the difference. In this guide, we’ll dive into the best Slayer upgrades in OSRS that will boost your efficiency, save time, and maximize your gains. Updated for 2025, these upgrades are must-haves for any serious slayer. Let’s get started!
Slayer isn’t just about killing monsters—it’s about doing it smartly. The right upgrades can cut down on tedious tasks, increase your XP per hour, and even turn a profit while you train. Without them, you’re leaving XP, loot, and convenience on the table. From gear to unlocks, these upgrades transform Slayer from a grind into a streamlined experience.
Boosting XP Rates
Upgrades like the Slayer Helmet (i) or the Bonecrusher directly impact your XP rates by enhancing combat efficiency or passively training Prayer. More XP per hour means faster progress toward your goals.
Saving Time and Resources
Tools like the Slayer Ring or Soul Bearer save you trips to the bank, letting you stay in the action longer. Time saved is XP earned, and that’s what we’re after.
Maximizing Profit
Some upgrades, like Bigger and Badder, unlock superior monsters with better loot tables. More loot equals more gold, making Slayer a money-maker as well as a skill trainer.
Top Gear Upgrades for Slayer
Your gear is the backbone of Slayer efficiency. These items are the cream of the crop, offering combat bonuses, utility, and convenience. Here’s what to prioritize:
Slayer Helmet (Imbued)
The Slayer Helmet (i) is the undisputed king of Slayer gear. It combines multiple protective items (Black Mask, Nose Peg, Earmuffs, Facemask, Spiny Helmet) into one slot while boosting your accuracy and damage by 16.67% for melee and 15% for ranged/magic against assigned tasks. You’ll need 400 Slayer points to unlock the ability to craft it, plus 1,250,000 Nightmare Zone points or 500 Soul Wars Zeal to imbue it.
- Why It’s Great: Saves inventory space and boosts combat stats.
- Best For: Every single Slayer task.
Bonecrusher
The Bonecrusher is a game-changer for Prayer training while slaying. Dropped by monsters in the Catacombs of Kourend or bought with Slayer points after the Morytania Hard Diary, it auto-buries bones for half the Prayer XP (full XP after Elite Diary). Pair it with the Catacombs’ Prayer restore effect to save on potions.
- Why It’s Great: Passive Prayer XP and fewer supply runs.
- Best For: Tasks with bone-dropping monsters like dragons or wyverns.
Expeditious Bracelet
Hate a task? The Expeditious Bracelet gives a 25% chance for a kill to count as two, speeding through undesirable assignments. Craft it with an opal bracelet and Level-1 Enchant or buy it from the Grand Exchange. It’s got 30 charges, so swap it on just before a kill.
- Why It’s Great: Cuts time on low-XP or boring tasks.
- Best For: Tasks like trolls or hill giants.
Slayer Ring
The Slayer Ring offers teleports to key Slayer locations (Slayer Tower, Fremennik Dungeon, Stronghold Slayer Cave, Tarn’s Lair) and lets you check task progress. Craft it with 75 Crafting or grab it from the GE.
- Why It’s Great: Reduces travel time significantly.
- Best For: Frequent travelers hitting multiple task spots.
Essential Slayer Reward Point Unlocks
Slayer points are your ticket to some of the best upgrades in OSRS. Earned from tasks (more from higher-tier masters like Duradel), these unlocks can reshape your Slayer experience. Here are the top picks:
Bigger and Badder (150 Points)
This unlock gives a 1/200 chance (or better with Combat Achievements) for a superior monster to spawn on-task. Superiors offer more XP and better loot, making it a no-brainer for profit and efficiency.
- Why It’s Great: More XP and loot per task.
- Best For: High-level slayers (70+ Slayer).
Malevolent Masquerade (400 Points)
Unlocks the ability to craft the Slayer Helmet. It’s a steep upfront cost, but once you’ve got the helmet, it’s a permanent upgrade that pays off every task.
- Why It’s Great: Enables the best Slayer headgear.
- Best For: Anyone serious about Slayer.
Need More Time? (100 Points)
Extends tasks like Kurasks or Dust Devils by 50-100 kills. Perfect for profitable or high-XP monsters you don’t want to end too soon.
- Why It’s Great: More kills = more loot and XP.
- Best For: Money-making tasks like Gargoyles.
Specialized Tools for Slayer Tasks
Beyond gear and points, some tools target specific tasks or mechanics, giving you an edge where it counts. These are niche but powerful.
Soul Bearer
Obtained from the Bear Your Soul miniquest, the Soul Bearer banks ensouled heads instantly. It’s clutch for tasks like demons or trolls, freeing up inventory for other loot.
- Why It’s Great: Saves bank trips on head-dropping tasks.
- Best For: Mid-to-high Slayer levels (50+).
Ash Sanctifier
Claim this from Tyss after the Kourend & Kebos Hard Diary. The Ash Sanctifier scatters demonic ashes for Prayer XP, much like the Bonecrusher for bones.
- Why It’s Great: Passive Prayer XP from demons.
- Best For: Tasks like Greater Demons or Abyssal Demons.
Leaf-Bladed Weapons
For Turoths and Kurasks, leaf-bladed weapons (sword, battleaxe, or spear) are mandatory. The Leaf-Bladed Battleaxe, in particular, is a strong mid-tier option droppable by Kurasks.
- Why It’s Great: Enables damage against specific monsters.
- Best For: Slayer levels 55+ with these tasks.

Tips to Get the Most Out of Your Slayer Upgrades
Got the upgrades? Here’s how to maximize them:
Task Management
Use Turael for point boosting (skip low-XP tasks) and switch to Duradel or Konar for high-XP/profit tasks once you’ve got a streak going. Block bad tasks with points to keep your list optimal.
Combine Upgrades
Pair the Bonecrusher with the Slayer Helmet (i) in the Catacombs for Prayer sustain, or use the Expeditious Bracelet with Bigger and Badder to blitz through tasks while still getting superior spawns.
Focus on Diaries
Complete diaries like Morytania and Kourend & Kebos to unlock the Bonecrusher and Ash Sanctifier. They’re free upgrades with massive long-term value.
With these best Slayer upgrades in OSRS, you’re set to dominate tasks in 2025. Whether you’re after XP, gold, or just a smoother grind, these tools and unlocks will get you there. Start with the Slayer Helmet (i) and Bonecrusher, then build up to Bigger and Badder and specialized tools as you level. Happy slaying!
