Many items and equipment sets have passive effects or set effects, which trigger on their own when equipped. These effects confer a wide variety of benefits, both combat and noncombat. In the case of a passive effect that applies to an equipment set, all items of that set must generally be equipped for the set to activate.
|Staff of the dead||Each combat spell cast with the weapon has a 1/8 (12.5%) chance of drawing its power completely from the weapon, negating its rune cost.|
|Toxic staff of the dead|

|Phoenix necklace||When the user is hit down to less than 20% of their maximum hitpoints (including being hit for 0), they will heal for 30% of their maximum hitpoints, destroying the necklace in the process.

|Amulet of the damned||Provides buffs to full barrows equipment sets in addition to their normal passive effects.|
|Serpentine helm||Grants immunity to poison and venom and gives a 1/6 chance to inflict venom on your target whenever you are attacked.|
In order for a set effect of Barrows equipment to trigger, all four pieces must be worn: Head, body, legs, and weapons.
|Ahrim's set||Blighted Aura - Magic attacks have a 25% chance of lowering the target's Strength by 5 levels.|
|Dharok's set||Wretched Strength - Dramatically increases maximum melee damage as hitpoints decrease. This is the only Barrows set effect that is always active.|

Void Knight equipmentEdit
Void Knight equipment has a set effect, directed by the combat class of the worn helmet, that increases the user's damage and accuracy in the chosen style.
|Melee||+10% melee accuracy, +10% melee strength|
|Ranger||+10% ranged accuracy, +20% ranged strength|
|Mage||+30% magic accuracy|
God Wars Dungeon protectionEdit
Many pieces of equipment affiliated with the gods Saradomin, Zamorak, Armadyl and Bandos provide a passive effect that prevents followers of that particular faction from being aggressive within the God Wars Dungeon. This effect does not apply to the bosses or to their bodyguards.
Poison and VenomEdit
Some items have the ability to add weapon poison on it, which in turn makes the weapon poisonous such as the popular dragon dagger. When fighting an opponent, there is a chance of inflicting poison on them, starting at 6 damage with the highest weapon poison applied to the weapon. The damage will gradually decrease and will go away.
Venom works slightly differently to poison. Only a few items have the ability to inflict venom, namely items that are dropped by Zulrah. When fighting an opponent, there is a chance of inflicting venom on them, starting at 6 damage and will gradually increase to a maximum of 20 damage per hit. Venom does not cure itself.
