Regular events are a large part of how Aion is played. The following should help you with a few common points of confusion.
Rifts
When a rift appears or changes location, you will see a zone wide message. You can also look up in the sky for a blue vortex to see if a rift is currently available in the zone. If you are having trouble locating a rift, I suggest asking fellow players in the area to link the current location.
You can also search for a Rift Map on Aion fansites, and use the map to check locations. Please be aware the rift location can change every hour real-time, and each rift has a limited number of players that can pass through before it disappears.
“Unable to enter the Arena at this time” message
If you try to enter the Arena of Chaos or the Arena of Discipline outside of the normal hours that they are available, you'll receive a message saying that your character is “unable to enter at this time.” This is normal, but it does mean that you won’t be able to take part right away.
In order to access these Arena instances, you'll need to make sure it's the appropriate time of day, and that your character has an Arena Ticket in their inventory. The Arena of Chaos and the Arena of Discipline can only be accessed during the below times (in server time):
Weekday (Monday - Friday) – 10 a.m. to 2 p.m.; 6 p.m. to 2 a.m.
Weekend (Saturday/Sunday) – 10 a.m. to 2 a.m.
NOTE: The Discipline Training Grounds and Chaos Training Grounds can be accessed at any time.
Arena of Chaos cooperation
It's not uncommon for two or more players to work together in the Arena of Chaos. In some cases there may be a pre-planned group. Other times, temporary alliances form during the course of battle. Given the free-for-all nature of this arena and the fact that there is always strength in numbers, it is inevitable that combatants will try to combine forces.
While there are measures in place to discourage the use of pre-planned teams, teamwork of any kind is allowed in the Arena of Chaos. In these situations, you should try to fight fire with fire.
For example, if you see some of the combatants running around together, you could try to help another player that they engage to show that you are willing to work together until the group is defeated.
Dredgion Queue Time
When quick-queuing to enter the Dredgion, it may take a while to find a team. The matchmaking system tries to create balanced teams based on class, and this can result lengthy wait times.
It's also possible that a group won't form at all, if a balanced team can't be created. For example, if there are 10 players in line but none of them are healers, a group won't be created, because the matchmaking system wants to make sure there's a healer in your party.
In order to prevent this from happening, finding a group to share a queue is a good idea, as it can result in much more consistent and expedient matchmaking.
