Dynamic events refer to any event that occurs in a persistent area as a result of players interacting with and exploring the world. They are called "dynamic" because there are multiple outcomes that also result in new events, creating a cascade effect. Once an event has triggered, it will develop whether or not a player attends it. Because of this, there is no real concept of failure or success – the result of any event will simply cause a change in the surrounding area. For example, if monsters are successful in raiding an area, they may become strong enough to occupy a fort, which could then be taken by players.
Events are designed to replace traditional MMORPG quests - players are notified when there is a new event nearby rather than looking for an NPC with an exclamation mark over their head. Traditional quests have negative repercussions such as spawn camping and kill stealing. Guild Wars 2's dynamic events prevent these issues by promoting player cooperation by rewarding all players that participate in the event 100% of any experience gained without the need to form a party. To keep a consistent level of difficulty along with increased participation, an event will scale dynamically based on the number of active participants. Not all events require combat to complete.
Dynamic events are cyclical in nature and the events are generally chained together. Events do not necessarily follow a fixed schedule, and may only trigger if certain conditions are met - for example, if a snow storm strikes an area, or if night falls on a graveyard. Many events are triggered by the presence of a player entering their immediate areas. Once an event has triggered, it will continue to progress whether or not players participate in that event. Although the repetitive nature of events means that consequences are ultimately temporary, the state of some events can persist for days, or until the next server reset or update, unless a player comes along and does something to progress the event or chain of events. Each event has an NPC associated with it with whom the player can talk to learn more about the story and lore behind the event.
In addition to single events, several common types of event chains can be observed: Chains of events which progress linearly and repeat after a short while; conquest-like battles, often part of meta events, in which players side with an allied faction to fight enemies and attempt to capture multiple locations or take down several enemy forces, after which the enemy attempts to take them back, and succeeds unless enough players are there to participate.
The possible event states are:
- Active – The event is running now
- Success – The event has succeeded. During this state NPCs may have different dialogs and offer certain services. And the following events of a chain of events may start within a few seconds.
- Fail – The event has failed
- Ready – The event is inactive, and will only become active once certain criteria are met. Such as talking to an NPC (NPC has wagon wheel or orange slice above their head) like Ine Duran.
- Preparation – The criteria for the event to start have been met, but certain activities (such as Secrets in the Swamp prior to Defeat the shadow behemoth) have not completed yet. After the activities have been completed, the event will become Active.
The foremost requirement of an event is being in the right place at the right time. Events can be discovered in a number of ways, such as exploring the world, conversing with non-player characters. Whenever a player comes within range of a new event, a New Event Nearby notification appears on screen along with an event assistant entry on the right-hand side. In the cases where the event occurs above or below the player, for example up a mountain or while swimming, a marker is used to indicate an up or down direction. The player map is also updated with a variety of event-related markers for as long as a player is within the events range. Should a player wander away from the event for too long, the player will be notified for being inactive for that specific event and will no longer gain event reward should the event be completed.

Events scale both up and down according to the number of players who are currently participating.  Events can scale in a number of ways:
- Enemy level can be increased
- Enemies can gain new abilities
- New enemy types may appear, including veterans, elites, or even champion versions
- Enemy count can be increased
- Objective requirements may increase
Champion enemies associated with the event will never increase in level due to scaling; this often results in elite foes that are more dangerous than the champions.
Events will scale according to the number of players around. Even a player that is not participating will scale the event up. A player that moves away, either by walking or waypointing, will immediately scale the event down.
Separate from event scaling, Group Events are different in complexity and/or difficulty from other events of the surrounding area. Group Events are listed in the event assistant with "[Group Event]", and like other events are marked on the map and compass. As their name implies, they are designed to be done with groups rather than individuals as they are unlikely to be solo-able (though some can be with patience and tactics).
A list of group events can be found on Category:Group events.
Meta events are a series of dynamic events that tells the story of an explorable zone. Meta events are displayed in the Event assistant stating if the meta event is inactive or the actual dynamic event that marks the state of the meta event.
Certain events follow after other events without being part of a meta event. These chained events are mechanically identical to meta events, but they lack interface indicators like meta events have.
At the end of an event, NPCs part of a chain will often talk to each other or to the player characters, build or repair structures, or run to another location at the end of an event. Shortly after that another event or additional rewards such as NPCs opening temporary shops may follow.
Once an event is completed, everyone who actively participated will receive experience, karma, and coin. The amount is based on the level of the event, the level of the player, the medal ranking, and whether the event was successful. If the level of the participant is below or equal to the level of the event, the reward is based on the level of the event. A dynamic event rewards 7% of experience required for the next level for players of the same level of the event. If the level is higher than the level of the event, the player will receive the base reward and an additional portion that scales with the difference in level. Keep in mind that level scaling for the area still occurs and the effective level of the player will be likely be one or two levels higher than the event. Participation can be very difficult for players more than a few levels below the event due to level scaling. Players with a difference of 10 or more levels are not able to participate and receive a ranking for the event.
If the player is upscaled in level, such as with the case of the Lost Shores and The Secret of Southsun releases, the reward will be based on the level of the player rather than the effective level or the level of the event.
If an event fails, players receive no karma and half the experience and coin reward of their current medal ranking for the event:
Some events may have additional rewards such as:
- Chests and bonus chests
- NPCs offering products or other services.
- Allowing access or making access easier to certain locations such as jumping puzzles, vistas, points of interest, mini-dungeons and dungeons.
- Spawning charmable animals.
In order to prevent griefing, ArenaNet has added several measures to prevent a group of players from spoiling the event for others:
- Events never encourage player conflict.
- They are designed to avoid including fail conditions that can be triggered by players, although they can fail if parallel events in the chain fail.
- Higher-leveled players are scaled down in areas that are intended for lower leveled players.
- When a character completes an event, whether the event ended successfully or not, they will occasionally shout out one of the following lines, depending on their race and gender.
|Asura|| Another victory.
That was easy.
|Charr||Done and done.|| All done here.|
|Human|| Done and done.
On to the next challenge.
|My task here is done.|
|Norn|| That's how it's done.
I call that done.
That's how you do it.
|Sylvari|| That's done.
That satisfied me.
Ah, it was nothing.
I'm ready for my next challenge.
