A secondary use of the Strength skill is determining which weapons a player may wield in combat. Generally, weapons which require a higher level to equip confer greater combat bonuses, providing some incentive for players to train the skill. All of the weapons in the following table are members only.
Conventional weapons used throughout Gielinor are not allowed in Daemonheim, so a separate set of metals is used during Dungeoneering. The metal types are classified by their "tiers", with tier 1 being the weakest and tier 11 being the strongest. Tiers 1 through 10 weapons may be player made or received as a drop from several monsters, but tier 11 items may only be received as a drop from boss monsters. Of the Dungeoneering weapon types, only mauls require a Strength level. Members-only weapons are indicated by (m).
Certain pieces of armour require a Strength level to wear. Though uncommon, a few such pieces exist. All of the pieces of armour in the following table are members only.
Most melee weapons provide a Strength bonus, which, along with a player's Strength level, determines how much damage a player may inflict in melee combat. Weapons which do not give a positive Strength bonus may be referred to as fun weapons. These weapons do not exist necessarily for use in combat; they may exist merely for aesthetic purposes.
Various items, potions, prayers, and familiars provide temporary boosts. Below is a list of all possible boosts to Strength.
Visible boosts are indicated in the stats interface by showing a level increase from the base level. Members-only boosts are indicated by (m).
