Stun

A stun is an effect that can occur during combat. When applied to a target, a stun prevents that target from attacking or moving for its duration. In addition, when used against a player target, it prevents that player doing any of the following:


 * Using any abilities, except for Freedom.
 * Changing prayers or equipment.
 * Consuming any food or potions. However, it does not stop the automatic consumption of a portent of restoration or a phoenix necklace (this is intentional), although it does prevent the target from equipping another of the latter.
 * Teleporting.
 * Casting spells.

The effects of a stun can only be removed via the Freedom (which also prevents further stuns for another six seconds) ability, although players can also provide themselves with temporary immunity to stuns by using the Anticipation ability. Stuns, along with all damage, can also be prevented with the Barricade ability. The ability Transfigure stuns the user for six seconds, then heals them afterwards for 250% of the damage they take in that time whilst providing a 15 second immunity to stuns.

Stuns in Thieving
A different form of stun occurs when a player fails at pickpocketing. This type of stun differs from a normal stun in several ways:
 * Pickpocketing stuns do not prevent players from using abilities or food, or changing prayers or equipment.
 * Anticipation will not prevent a player from being stunned by a failed pickpocket.
 * If Freedom is used, the player will be able to move immediately, but will still be unable to pickpocket until the stun's duration naturally runs out.

Trivia

 * Stuns existed before the Evolution of Combat. For example, Rammernaut, Night-gazer Khighorahk, and many summoning familiars could stun, although it was impossible to remove the stun without waiting for it to wear off.
