If you’ve ever wondered why players say the Slayer helmet is one of the strongest items in Old School RuneScape, the answer is simple: task bonuses directly boost your DPS. These bonuses don’t just increase your max hit — they also improve accuracy, making every fight faster and more efficient.
In this guide, we’ll explain how Slayer task bonuses work, how much DPS they add, and why the imbued version changes the game for ranged and magic. If you’re building an efficient account, track your growth using the OSRS DPS Calculator.
What Are Slayer Task Bonuses?
When fighting monsters assigned by a Slayer master, wearing a Black Mask or Slayer Helmet provides:
- +16.67% melee accuracy and damage (regular version).
- Imbued Slayer Helmet: Extends the same 16.67% bonus to ranged and magic.
This bonus is only active while on task. It doesn’t apply in PvP or against monsters not assigned.
How the Bonus Translates to DPS
DPS (damage per second) is a mix of how often you hit and how hard those hits are. The Slayer helm bonus improves both:
- Higher Accuracy → You land more hits, especially on high-defence monsters.
- Higher Damage → Each hit deals more damage on average.
- Stacking → The bonus multiplies with prayers like Piety, Rigour, or Augury and with potions like Super Combat or Ranging potions.
Example:
- Without bonus: Max hit = 30, DPS = 25.
- With Slayer helm: Max hit = ~35, DPS rises to ~29.
- With prayers and potions stacked: DPS jumps further, often above 35.
DPS Impact by Combat Style
Melee (Regular Helm)
- Slayer helm boosts both strength and accuracy.
- Crucial for melee Slayer bosses like Abyssal Sire or Cerberus.
- Works perfectly with Super Combat potions + Piety.
Ranged (Imbued Helm)
- Ranging DPS sees massive gains against Slayer monsters.
- Stacks with Rigour and Ranging potions.
- Especially valuable at tasks like Dust Devils, Abyssal Demons, or ranged Cerberus kills.
Magic (Imbued Helm)
- Magic DPS finally benefits with the imbued helm.
- Great synergy with Augury + Magic potion (or Imbued Heart).
- Key for magic-heavy Slayer tasks and bosses like Kraken.

Practical Effects in Gameplay
- Faster Kills: On-task DPS can cut kill times by several seconds, especially in Slayer boss fights.
- XP/hour Gains: Faster kills = more XP and profit per hour.
- Supply Savings: Higher DPS means fewer food and prayer supplies needed.
- Endgame Scaling: In raids or Slayer bosses, the DPS boost can rival or exceed gear upgrades worth millions of GP.
