Damage per second/Melee

This article is about calculating melee damage output. Melee damage is affected by the Equipment used, prayer, skill boosts and the monster being attacked.

There are various methods by which players can increase their potential Melee damage. The effects of most equipped items can be seen in the stats window (labelled as Stab, Slash, Crush and Melee Strength).

Effective level is affected by your current strength level multiplied by prayers used and skill level boosts.

To calculate effective strength level:

1. (Strength level + Strength level boost) * prayer modifier
2. Round down to nearest integer
3. If you're calculating for:
   • A player, +3 if they're using the aggressive attack style, or +1 if using controlled
   • An NPC, +1
4. +8
5. Multiply by 1.1 if wearing full melee void
6. Round down to nearest integer

Strength Level boost:

Prayer Multiplier:

The maximum hit is the largest hit you can possibly do with the current setup. It can be tested by using the Combat Dummy in a Player Owned House.

To calculate your maximum hit:

1. Effective strength level
2. Multiply by (Equipment Strength bonus + 64)
   • The Equipment Strength bonus can be found in the Equipment Stats window under 'Other bonuses'.
3. Add 320
4. Divide by 640
5. Round down to nearest integer
6. Multiply by target-specific gear bonus
   • If slaying monsters on task while wearing a black mask or slayer helm, gear bonus is 7/6. If killing undead monsters while wearing a salve amulet, gear bonus is 7/6, or 1.2 if using salve amulet (e) or (ei). Note that these two bonuses DO NOT stack.
   • If attacking another player who has the Protect from Melee prayer active, multiply by 6/10.
7. Round down to nearest integer

Effective level is affected by your current attack level multiplied by prayers used and skill level boosts.

To calculate your effective attack level:

1. (Attack level + Attack level boost) * prayer modifier
2. Round down to nearest integer
3. If you're calculating for:
   • A player, +3 if they're using the accurate attack style, or +1 if using controlled
   • An NPC, +1
4. +8
5. Multiply by 1.1 if wearing void
6. Round down to nearest integer

Attack Level boost:

Prayer Multiplier:

1. Effective attack level * (Equipment Attack bonus + 64)
2. Multiply by target-specific gear bonus
3. Round down to nearest integer

The Equipment Attack bonus can be found in the Equipment Stats window, and is labelled Stab, Slash, Crush. Use the value of whichever attack type you are using.

Gear bonus is the same as in Step Two.

The effective defence level is only used for calculating the defence roll for players, it is not used for monsters.

It is affected by the player's defence level multiplied by prayers used and skill level boosts.

To calculate your effective defence level:

1. (Defence level + Defence level boost) * prayer bonus
2. Round down to nearest integer
3. +3 if the player is using the defensive attack style, or +1 if using controlled
4. +8

To calculate a monster's defence roll, use the formula:

Target's Defence level is denoted by a shield icon on the target's wiki page.

To calculate a player's defence roll, use the formula:

Target's style defence bonus refers to its stab, slash or crush defensive stats, depending on the attack type used.

If Attack Roll > Defence roll:

Else

A small amount is added equal to the inverse of the maximum hit. This is because if you roll a 0 on a successful attack it will be changed to a 1.

To calculate the average damage per second (dps), divide the average damage per attack by the attack speed of the weapon in seconds.
