Calculation Notes

• DPS assumes continuous combat

• Special attacks not included

• Uses standard OSRS formulas

Max Hit Formula:

floor((Effective Strength × (Strength Bonus + 64) + 320) / 640)

Accuracy Calculation:

Based on your attack roll vs target's defense roll. Higher attack bonus and level = better accuracy.

DPS Formula:

(Max Hit × 0.5 × Accuracy) / Attack Speed

Use Aggressive stance when you don't need the accuracy bonus from Accurate stance

Prayer bonuses significantly increase both max hit and accuracy

Faster weapons aren't always better - consider the strength bonus too

Special attacks can provide DPS boosts but aren't calculated here
