Some weapons in RuneScape have special attacks available for them. There are many types of special attacks, from temporary boosts in stats, to strikes dealing extra damage.

In the combat interfaces of these weapons you will notice a special attack bar. If you click on the bar, then your character will initiate a special attack and use up some of your special attack power.

Different special attacks use up different amounts of power. If you do not have enough power for your weapon's special attack, you won't be able to use it. Your special attack power will slowly restore over time.

You may drink a recover special potion to recover a quarter of your special attack per dose- however there is a small recovery period before you may drink another dose. You may also wear a ring of vigour to reduce the cost of special attacks by 10% of the original usage amount.

Special Attacks are considered by many players to be very useful during combat and are also extremely helpful for skilling - for example, the enhanced excalibur's special attack can heal up to 200 LP (400LP if the Seer's Village Elite Tasks are completed). This is widely used while doing Pyramid Plunder for thieving.
