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.

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.
