Interpreting Your Result

The "Winner" is the weapon with the higher DPS value. However, you should also consider the "Time to Kill" (TTK), as a higher DPS doesn't always mean a faster kill if the mob has very low HP.

✓ Do's

  • Use this to decide which weapon to buy when you have a limited budget.
  • Always input the target's exact Defense level and bonuses for accuracy.
  • Compare weapons with their typical "Pairings" (e.g., Whip with Defender vs. 2H weapons).
  • Account for "Special Effects" like the Keris Partisans bonus against Kalphites.

✗ Don'ts

  • Don't rely on DPS alone for bosses with "Phases" or floor mechanics.
  • Don't forget about "Weapon Range"; a short-ranged weapon might lose DPS due to moving.
  • Don't ignore "Cost per Hour"; a 5% DPS increase might not be worth a 500k GP/hour usage cost.
  • Don't assume the best weapon for one boss is the best for another.

How It Works

The OSRS Weapon Comparison Calculator is the ultimate tool for choosing your gear. Instead of just looking at stats, this calculator runs full combat simulations to find the "True DPS." Whether you are choosing between a Whip and a Bludgeon or comparing the Fang to the Rapier, this tool gives you the definitive answer.

Formula Used

DPS = (MaxHit * Accuracy) / (AttackSpeed * 0.6)

Real Calculation Examples

  • 1Compare the Abyssal Whip + Dragon Defender vs. the Abyssal Bludgeon at Sarachnis.
  • 2Test the Osmumten’s Fang vs. the Ghrazi Rapier against high-defense bosses like General Graardor.
  • 3Find if the Bow of Faerdhinen (Bowfa) is better than a Blowpipe with Dragon Darts at Zulrah.

The Comprehensive Guide

OSRS Weapon Comparison Calculator: The Ultimate Guide to Gear DPS

In Old School RuneScape (OSRS), gear selection is everything. With hundreds of weapons, from the classic Abyssal Whip to the legendary Scythe of Vitur, knowing which tool to bring to a fight is the difference between a 2-minute kill and a 3-minute kill. Over thousands of kills, that extra minute adds up to hundreds of hours. Our OSRS Weapon Comparison Calculator is designed for the 2026 player who value efficiency, accuracy, and profitability. We don't just look at "Strength Bonus"—we calculate True DPS.

What is DPS and Why Does it Matter?

DPS (Damage Per Second) is the only metric that truly matters in OSRS combat. It combines your:

  • Max Hit: The highest number you can roll.
  • Accuracy: Your chance to land a hit (non-zero) on a specific target.
  • Attack Speed: How often you swing your weapon.

A weapon with a massive max hit but a slow attack speed (like the Elder Maul) often has lower DPS than a fast, weak weapon (like the Toxic Blowpipe). Our calculator does the heavy lifting, running the 0.6-second game tick math so you don't have to.

Weapon Meta Comparison Table (2026)

This table showcases how some of the most popular weapons compare across different defense tiers.

Weapon Attack Speed Primary Use Case Performance vs. Low Def Performance vs. High Def
Abyssal Whip 4-Tick General Slayer Excellent Moderate
Osmumten’s Fang 5-Tick High-Level PvM Good Best in Slot
Scythe of Vitur 5-Tick (3 Hits) Large Bosses (3x3+) God Tier Varies
Ghrazi Rapier 4-Tick Low-Def Slayer Best in Slot Poor
Bow of Faerdhinen 4-Tick All-Around Ranged Excellent Great
Toxic Blowpipe 2-Tick Small Mobs/Minions God Tier Fail

How to Compare Weapons Effectively

To get the most accurate result from our OSRS Weapon Comparison Calculator, you need to provide accurate inputs. Here is the checklist:

  1. Input Your Character Stats: Your Attack and Strength levels are the foundation of your DPS.
  2. Input Target Stats: Use the "NPC Search" feature or manually enter the target's Defense level and defensive bonuses (Stab, Slash, Crush, etc.).
  3. Select Your Prayers: Never compare weapons without Piety or Rigour enabled; the multipliers affect fast and slow weapons differently.
  4. Add Gear Buffs: Don't forget the Slayer Helmet, Void Armor, or Salve Amulet bonuses.

The "Fang" Paradox: Accuracy vs. Speed

One of the most complex comparisons in 2026 is the Osmumten's Fang. The Fang has a unique "Double Rolling" accuracy mechanic. This means it rolls for success twice and takes the better of the two results.

Why this matters: Against a boss like General Graardor (250 Def), a 4-tick weapon like the Whip will "zero" 40% of the time. The 5-tick Fang will only "zero" 15% of the time. Despite being slower, the Fang's consistency makes it the clear winner. However, against a Slayer Monster with 0 Defense, the Whip's speed allows it to attack 25% more often, making it the superior choice. Our calculator identifies this "Crossover Point" automatically.

Ranged Comparison: Bowfa vs. Blowpipe

The Toxic Blowpipe was once the king of OSRS. Today, the Bow of Faerdhinen (Bowfa) with full Crystal Armor is the standard.

  • Blowpipe: High reliance on Dragon Darts and low-defense targets. Best for training or healers in Inferno.
  • Bowfa: No usage cost (if corrupted), massive range, and high accuracy. Best for long-term Bossing (Zulrah, GWD, Muspah).
Use the calculator to see where your specific Ranged level makes the Blowpipe fall off.

Magic Meta: Shadow of Tumeken

In 2026, the Shadow of Tumeken from the Tombs of Amascut has redefined Magic DPS. It triples your magic accuracy and damage bonus from gear. This makes it so powerful that it often beats melee at bosses where magic was previously ignored. When comparing the Shadow to a Sanguinesti Staff, our calculator accounts for this 3x multiplier to show you the massive 20%+ DPS jump.

The Cost of DPS: GP per Damage

A "10% DPS increase" sounds great until you realize it costs 2,000,000 GP per hour in charges (e.g., Scythe of Vitur or Shadow of Tumeken).

Our calculator includes a "Profitability Filter." It subtracts the cost of potions, blood runes, and vials of blood from your expected loot per hour (based on kill speed). Often, the "Second Best" weapon is actually the "Best" for your bank account.

The "Fang" vs. "Rapier" Debate

Scenario: Comparing the Osmumten’s Fang to the Ghrazi Rapier against General Graardor (Defense 250).

Outcome: The Fang wins by 12% DPS due to its accuracy roll. At Sand Crabs, the Rapier wins by 15%.

Blowpipe Dart Comparison

Scenario: Comparing Mithril Darts vs. Amethyst Darts at Vorkath.

Outcome: Amethyst Darts provide 8% more DPS. Over a 50-kill task, this saves ~12 minutes of real-world time.
