Fear effects are a form of crowd control that makes a victim to run in random directions, unable to perform most actions for a period of time. Feared creatures have a small chance to break Fear when damaged. Any Fear, no matter the duration listed, will last a maximum of 12 seconds when used against players in PvP, and fear is affected by diminishing returns.
Fear, among all crowd control types, is unique in that the victim runs around, sometimes quite a distance before the effect ends. Players affected by it may run into awkward areas (though they will not fall off cliffs) or into more enemy monsters or players that may attack. Monsters affected by Fear may also run into groups of monsters, alerting their friends which then come running into the fight. The fact that it has a somewhat low chance of breaking on damage means that it can be as effective as a Stun with some luck, or more so if the enemy runs far away and must run back to you while you attack; on the other hand it can last too long and the enemy runs into a group of fellows, or break after only a hit or two.
Many Fear effects are magical and can be dispelled or reflected; many are Shadow and are affected by Shadow Resistance.

Also dealing fatal damage, a high shadow resistance, or avoiding the range or area the user can hit with fear are all viable ways to stop the Fear from happening. At the present time, there are thirty-one race/class combinations capable of either dispelling Fear, becoming immune to at least one Fear, or are capable of stopping the spell.
