Weapon Special attack

Special attacks are attacks that do something extra than to their normal style of attack. They are usually only seen in Dragon weapons, but some weapons not having a weapon at this level have a special attack at Rune weapon level. Special attacks have an energy bar that is drained when you use a special attack, this is drained of varying amounts according to which weapon is used.

Dragon Dagger

 * Puncture. 2 very quick strikes with increased attack and strength.
 * 25% Drain. Dragon Dagger is the most common player killing weapon in the P2P version of runescape as it hits 2 times, and can easily kill an unaware player as it can hit well over, for example, 50 (25,25 using special attack) if you have the required strength level. If that doesn't kill a foe, poison can (assuming the dagger is poisoned).
