Stun effects are a form of crowd control that will cause a victim to be unable to move or perform most actions for a period of time. Stuns are significantly more effective than snare or root effects, since they prevent the victim from taking any action. Consequently, stuns are almost always very short duration effects.

Stun effects are similar to Sleep Effects in that they also prevent a victim from taking action. However, the Undead racial ability Will of the Forsaken (which removes Sleep, Charm, and Fear effects) will not remove a stun. Additionally, stuns are not broken by damage.

Examples of abilities that stun opponents:

Note that due to diminishing returns, after three stuns (not to be confused with disorients) within a short period of time, the target will become temporarily immune. For example, if the mage ability [Impact] is triggered more than three times in a short period of time, the target will show immunity towards a fourth Impact. There are however several diminishing returns categories, one for activated stuns, which include most stun effects, and one for proc stuns, which include the stuns from procs, as well as one specifically for Cheap Shot. Using stuns in one category will not affect the duration of stuns in the another category. Also, unlike many crowd control effects, most stuns suffer diminishing returns even in PvE encounters.
