Stun (status)

Being stunned is a temporary status that causes an affected entity unable to do anything for a short period. Most types of stuns are indicated by yellow circling birds around the head of the entity.

Thieving
When a player unsuccessfully attempts to pickpocket a target, they are temporarily stunned, as well as take a specific amount of damage. The amount of time they are stunned for varies from target to target, ranging from four to six seconds.

Weapons
Some melee weapons are capable of stunning.

Special attacks
The following weapons share the same special attack, Shove, which stuns a target for three seconds:
 * Dragon spear
 * Zamorakian spear

The special attack can only be used on targets that take up one square.

Blackjacks
All blackjacks share a passive effect that will occasionally stun the target upon hitting, causing them to briefly stop attacking.
