Combat damage mechanics is a mechanic topic that Gnomonkey covers in 1 video on 2024-07-07. This article is a stub: his statements are grouped by type, repeated ones merged.

Methods

  • An OSRS attack first rolls accuracy: a random number based on your current attack level (including potion boosts), prayer and attack style, rolled against the target's defence level multiplied by its defence bonus for that style; if your number is bigger you hit, otherwise you hit zero.1
  • When an attack lands, the damage is a random number from 1 up to your max hit, so each additional max hit is an extra pip on your die.2
  • Ranged and magic work the same way, with ranged checking the monster's defence level and ranged defence, and magic checking the monster's magic level and magic defence; he notes weakness changes complicate this slightly.3
  • Combat style chooses which accuracy bonus of your gear is rolled, and styles give hidden level boosts: block gives +3 defence and slash on a rune scimitar gives +3 strength.4
  • Ranged on rapid is a tick faster for all weapons, which outweighs even potential max hit gains from accurate every single time.5
  • Special attacks always use their own style regardless of the selected stance: if you put claws on stab, you roll the lower stab bonus against the enemy's slash defence, lowering accuracy against stab-weak enemies.5

Tips

  • This is why people barrage in melee gear: against a monster with 1 magic level you basically never splash.4
  • You basically always want your weapon on aggressive for the extra +3 strength levels; magic never gets increased max hit from style, so it matters much less.5

Gnomonkey's opinion

  • Gnomonkey says things that increase max hit are usually more important than accuracy, because a bigger die matters more than a 1% higher chance to roll the die.3
