Equipment tier is a hidden value for worn equipment that determines accuracy and damage of weapons and the armour value, damage bonus, and life point bonus of armour. It is often, but not always, the wield/wear requirement.
Effects of equipment tier[edit | edit source]
The following bonuses and effects are influenced by equipment tier:
- Equipment bonuses:
- Weapon accuracy
- Weapon damage
- Armour value
- Armour damage bonus
- Armour life point bonus
- Damage reduction
- Ability damage
- Ability scaling, including:
The following bonuses/effects are not influenced by equipment tier:
- Equipment bonuses:
- Prayer bonus
- Most set effects and passives
Armour tier penalty[edit | edit source]
The main types of armour - tank, power, hybrid, PvP - have varying penalties for calculating their equipment stats from their tier.
If a piece of armour has tier , its bonuses are with effective tier:
|Type||Armour value||Damage bonus||Life point bonus|
In addition, most standard metal (bronze-dragon, novite-primal) chainbodies, square shields, and non-full helmets (formerly known as medium helmets) suffer a two tier penalty to their armour and life point values. Here, they are treated as normally tiered items - e.g. the rune chainbody is treated as a normal tier 48 item, not a tier 50 item with a penalty.
Imperfect tiers[edit | edit source]
Equipment with all their relevant bonuses reflected by a single tier (and correct type and speed) are referred to as perfectly tiered. For example, the drygore mace is a main-hand fastest-speed melee weapon with tier 90 accuracy and tier 90 main-hand fastest-speed damage; thus, it is perfectly tiered.
Imperfectly tiered equipment is not perfectly tiered. This can be due to one or more of the following:
- Mixed tiers - equipment with bonuses that correspond to different tiers, for example:
- Incorrect speed weapons have a damage value that corresponds to the same tier but a different speed. This often applies to weapons not intended for use in combat. For example:
- Incorrect hand weapons have a damage value that corresponds to the same tier and speed but is for a different hand. For example:
- Exquisite 2h sword is a two-handed average speed melee weapon with a tier 9 and tier 36 variant; these have tier 9/36 accuracy, and tier 9/36 main-hand average damage (about 2/3 damage that they should have)
- Most pickaxes and hatchets, e.g. the crystal pickaxe, are main-hand weapons with off-hand damage (so half the damage of a normal main-hand weapon of that speed)
- Custom bonuses can be found on equipment where the bonuses do not line up with a tier at all. For example:
- Achromatic Balmung and its variants have tier 70 accuracy but damage around halfway between tier 71 and 72; as tier isn't fractional, this is a custom bonus.
Formulae[edit | edit source]

During this section, the following formula is defined:
Where is tier.
Also in use is the floor function , which always rounds down: i.e. ,
Weapon accuracy[edit | edit source]
The accuracy of all weapons is dependant solely on tier; class, hand, and speed do not affect it. It is calculated as .
Weapon damage[edit | edit source]
The displayed weapon damage is a simple multiple of the weapon's tier. The multiplier varies with hand, speed, and weapon type.
The following table applies to the shown bonuses of all melee weapons, all thrown weapons, and all ranged weapons which generate their own ammunition (e.g. the crystal bow). For magic and other ranged weapons, the hover-overs won't directly show these numbers, but the combined effect of ammunition/spell should give damage in this table as well.
- Other ranged weapons
Most ranged weapons get some or all their damage from the ammunition in use. Those that generate their own ammunition and thrown weapons have a damage value using the above table.
- Main and off-hand weapons that do not provide their own ammunition do not have a damage bonus (generally dual-wielded crossbows)
- Ammunition provides the same bonus as a main-hand fastest weapon:
- Two-handed fast weapons (most shortbows) have a damage bonus of
- Two-handed average weapons (most two-handed crossbows and longbows, but not shieldbows) have a damage bonus of
- Shieldbows (which are two-handed average) have a damage bonus of
The damage for ammunition and weapon are added together with speed/hand weightings, with the overall result giving the above table. The damage is capped at the lowest of the tiers of the ammunition and the weapon.
Magic weapons do not have a damage bonus, as damage is provided by the spell selected and scaled to the speed of the weapon. The overall damage will correspond to the above table. Damage is capped at the lowest of the tiers of the spell and the weapon.
- Ability damage
When using abilities, the damage of the weapon is scaled to its speed. Thus, it doesn't matter exactly what your exact damage bonus is, your ability damage is:
- Two-handed or dual-wielding (when using the same tier in both hands):
For ranged and magic, the tier used to calculate damage is the lower of the tier of the weapon wielded and the ammunition/spell used.
Armour value[edit | edit source]
Armour value is calculated similar to accuracy, with a multiplier for the slot. Effective tier penalties apply for hybrid and power armour.
- Set (of all the same tier):
- Head, body, legs, gloves, boots:
- Head, body, legs, gloves, boots, shield:
- Head, body, legs, gloves, boots, cape, ring:
- Head, body, legs, gloves, boots, cape, ring, shield:
Armour damage bonus[edit | edit source]
Damage bonus, much like weapon damage, is a simple multiplier of the tier. This is scaled with speed and hand to add to weapon damage/ability damage. Damage bonus only depends on tier for the following slots (the damage bonus of capes, rings, necklaces, etc does not depend on tier):
- Set (all parts, same tier):
Armour life points bonus[edit | edit source]
Life point bonuses only apply to shields tier 70 and greater, and head, body, and leg armour tier 80 and greater.
Damage reduction[edit | edit source]
The damage reduction of armour depends on the slot, type, and tier. PvM damage reduction is exclusive to tank armour and shields, while PvP damage reduction is available to all armour types.
The 2-tier penalty for medium helmets, chainbodies, and square shields does not apply here.
- PvM damage reduction (tank armour only)
- PvP damage reduction
|Tank and PvP||Power and Hybrid|
Dungeoneering tier[edit | edit source]
For most equipment, Dungeoneering tier corresponds to equipment tier using the following formula:
