Knock-out aura

Knock-out is an aura available as part of the Members Loyalty Programme and can be purchased from Xuan in Burthorpe or Varrock, for 3,500 Membership Loyalty Points. Upon its release, it was on sale for 400 points instead of 3,500. This aura increases hitchance on a target if it's health is 15% or lower. It has an activation period of 1 hour and a recharge time of 4 hours. Destroying and retrieving the aura will reset its recharge period back to 4 hours. As with all auras, it automatically deactivates upon being unequipped and like most combat enhancing auras; it does not work in PvP. Also, as with all auras, if the account using it is logged out while the aura is activated, the timer will continue to run out.

When the aura triggers then it emits a blue-white flash around the player, but after the Evolution of Combat update this flash no longer appears.

While the aura is active, any successful hit will be increased to kill the monster as long as its LP is low enough.

Note: It's important to note that people have found the knock-out aura does not work with high level npcs such as General Graardor, Nex, the Corporeal Beast and the King Black Dragon, however it does work on Bork & Jad.

Master knock-out (tier 3)
Master knock-out is a tier-3 aura that can be bought from the Loyalty Programme Shop for 50,000 Membership Loyalty Points, but only after the standard Knock-out aura is purchased. The aura will remain activated for 1 hour and has a recharge time of 4 hours.

Upon activation, it will guarantee an increased hitchance to an enemy in combat when the enemy is below 15% health. This effect will not work in player vs player combat.

This aura is usable for all three styles of combat, and will activate under normal conditions regardless of the style of combat used.

Trivia

 * When you activate it and log on to an F2P world you will still see the blue flash around your player when you kill an NPC.
 * The knock-out aura does not work with a Balmung.
 * The knock-out aura doesn't work when firing with a Dwarf multicannon. Only the hits of the player will be affected, not those of the cannon nor do hits from familiars.
 * There also is no intermediate Greater Knock-out aura, which makes this aura unique.
