The Equipment Stats interface (Click for greater detail)
Equipment Stats (often referred to as equipment bonuses, or simply stats or bonuses) are bonuses found in the Worn Equipment section of the interface which are determined by the equipment a player is wearing. Equipment bonuses are split into three categories: Attack bonus, Defence bonus, and Other bonuses.
All armour and weapons give a value for each bonus, with the strongest equipment giving the highest bonuses. Equipment bonuses,
combined with a player's levels in combat skills and their chosen attack style are formulated into the calculations made by RuneScape in extremely short amounts of time which determine the amount of damage is inflicted and received in return, as well a
Equipment bonuses are highly important to certain aspects of RuneScape such as player killing in Bounty Hunter and fighting in the Duel Arena for large stakes because players will put large amounts of time into determining what combination of equipment will give them the best chance of success.
The information from the Attack types article might support the following section.
While in combat, a player's attack bonus in the attack type of their chosen attack st
yle, compared to their opponent's defence bonus in that attack style, determines how likely the player is to hit.
In short, a higher attack bonus in a particular style increases the chances of dealing damage to an opponent.
Corresponding with the five different attack styles, the five attack bonuses are:
Stab
Slash
Crush
Magic
Ranged
Defence bonuses
Bonuses to defence serve to protect combatants from damage. The higher the defence bonus in a particular style, the lower the chance of taking damage from an attack of that style.
As the defence bonuses correspond with the attack bonuses, there are six defence bonuses; one for each attack style and an extra, as there is no Summoning attack bonus. A higher bonus thus lowers the chance of being dealt damage by NPCs or players using the particular attack style, plus lowering the average amount of damage dealt when it connects. Maximum damage stays the same.
Corresponding with the six different defensive styles, their defence bonuses are:
Stab
Slash
Crush
Magic
Ranged
Summoning
Absorb Melee
Absorb Ranged
Absorb Magic
Other bonuses
Strength: (colloquially str bonus) Two stats affect a player's maximum melee hit: their strength level (see Strength) and their equipment's strength bonus. The two of them calculated together result in the players max hit. See maximum melee hit for the formula used to calculate max hit.
A player with level 75 strength with a strength bonus of 0 would have a max hit of 90, but the same player with a strength bonus of +105.0 would have a max hit of 220. This is a clear illustration of why strong weapons are effective: the higher the strength bonus, the higher the maximum hit.
Ranged Strength: This stat that affects the maximum hit that a player can do with range. Only ranged ammunition (arrows, bolts, javelins, etc.), the crystal bow and the sling (which doesn't use amunition) have this bonus. Gem tipped bolts have a slightly higher ranged strength than un-tipped bolts (ex. Bronze bolts have a ranged strength of 10.0 while opal tipped bronze bolts have a ranged strength of 14.0).
Prayer: Decreases the drain rate of prayers, or the amount of time a prayer takes to drain 1 prayer point. A prayer bonus of +15 will add 50% extra time to the use of all prayers, and a bonus of +30 will cut the drain rate for every prayer in half (meaning points will last twice as long). See prayer bonus.
Magic Damage: A percentage bonus found on some staffs and other equipment. Items, such as the Ancient Staff, will give you a percentage bonus to your damage. In this example, the Ancient Staff will give you a 10% magic damage bonus, making the max hit of a spell such as Ice Barrage 330 LP, versus 300 normally. You can also get a percentage increase to your magic damage if your magic level is boosted beyond its actual level (by drinking potions, for example). The percentage increase can be calculated by taking the number of levels you have boosted and then multiplying it by 3. For example, the extreme magic potion gives 21% extra magic damage, which is 7 boosted levels multiplied by 3. As the boost to your magic level reduces, so will this percentage decrease.
