Damage Formula:
From: | To: |
In Old School RuneScape (OSRS), damage calculation determines how much damage you deal to an opponent in combat. It combines your maximum potential hit with your accuracy chance against the target's defenses.
The calculator uses the damage formula:
Where:
Explanation: This formula gives the expected damage per attack, accounting for both how hard you can hit and how often you hit.
Details: Understanding your expected damage helps optimize gear setups, compare weapons, and estimate kill times. It's essential for efficient PvM (Player vs Monster) and PvP (Player vs Player) combat.
Tips: Enter your max hit (found using other calculators or in-game testing) and your accuracy (typically calculated by other tools or based on experience). Both values must be valid (max hit > 0, accuracy between 0-1).
Q1: How do I find my max hit?
A: Max hit depends on your strength level, equipment, prayers, and potions. Use a max hit calculator or test in-game with controlled conditions.
Q2: How is accuracy determined?
A: Accuracy depends on your attack level, equipment, opponent's defense, and other bonuses. Complex formulas determine your exact hit chance.
Q3: Why is my actual damage sometimes different?
A: This calculates expected damage. Actual combat has randomness - you might hit your max or miss completely in any given attack.
Q4: Does this account for special attacks?
A: No, special attacks often have unique mechanics. You may need to adjust max hit or accuracy for specials.
Q5: How can I improve my damage output?
A: Increase your max hit (strength bonuses, potions, prayers) or accuracy (attack bonuses, potions, prayers), or use weapons with faster attack speeds.
