AION 2 Dimensional Invasion: Beritra Air Raid, Keys & Loot
AION 2 Dimensional Invasion explained: the hourly :30 schedule, Beritra Air Raid and the other two invasions, daily reward keys and what each clear pays.
AION 2 Dimensional Invasion is a free field event that opens every hour at :30 for level 45+ characters: you jump into an arena, fight waves of Balaur, wraiths or spirits for about ten minutes, and finish on a boss. The three versions are Beritra Air Raid, Accursed Sword and Incursion of the Spirits. This guide covers the schedule, how to join, how the daily reward keys work and what each clear actually pays.
What Dimensional Invasion is in AION 2
Dimensional Invasion is a timed open event, not a dungeon. A rift opens, an invading force pours into a fenced arena, and every player of your faction who joins fights it together. There is no entry ticket, no item level check and no party finder: you show up, you fight, you get a reward screen at the end.
Each round picks one of three invasion types, and the order is not fixed, so you cannot plan around a specific one. All three use the same schedule, the same reward tables and the same daily key, so in practice it does not matter much which one you get. What changes is the enemy mix and the final boss.
It is one of the easiest repeatable sources of Enhance Stones and Centuryroot Tokens in the game, which is why most players slot one or two rounds into their daily routine next to the items on our AION 2 daily and weekly checklist.
Dimensional Invasion schedule and how to join
The event runs 24 times a day, at half past every hour. The game client lists a 3-minute gathering period followed by roughly 10 minutes of fighting. The Shugo Festival runs on the hour, so the two never overlap: you can do a Festival at :00 and an invasion at :30 in the same hour.
- Reach level 45. The reward tables start at 45, so finish the campaign push first. Our AION 2 leveling guide covers the fastest route.
- Watch for the :30 alert. When a round opens, a notification and a timer icon next to the minimap show the active invasion.
- Join during the gathering window. Click the icon or follow the marker to the entrance. Elyos entrances are in Verteron, Asmodian entrances in Altgard, and you are moved into the arena.
- Fight until the boss falls. Waves come first, then the boss appears in the middle of the arena near the end of the round.
- Spend a key on the reward screen if you want the big package. You can clear without a key and still get the regular rewards.
If you miss the gathering window, wait for the next round at the following :30. With 24 rounds a day there is always another one within the hour.
The three invasions: Beritra Air Raid, Accursed Sword and Incursion of the Spirits
AION 2 Dimensional Invasion types (checked November 10, 2026)
| Invasion | Story | Enemies | Final boss |
|---|---|---|---|
| Beritra Air Raid | A Beritra Dredgion Transporter drops a Balaur strike force into the field | Drakan Air Raiders, Armed Air Raiders, Air Raid Warmages, Destruction Engineers, Air Raid Rovers | Air Raiders Captain Tetrata |
| Accursed Sword | A cursed blade on an old battlefield holds a fallen Daeva’s soul | Corrupted forces bound to the cursed sword | Executor of the Magical Sword |
| Incursion of the Spirits | Grandios leads spirits of Etheria through a rift into Atreia | Elemental spirits of Etheria | Grandios, the Spirit Ruler |
The bosses are Hero rank and take most of the round’s damage, so they also hand out most of the score. Tetrata and the Executor are Cogni-type enemies and Grandios is Natura, which matters only if you run gear or pet stats aimed at one type. Our AION 2 pets guide explains how Genus Insight boosts damage against each type.
Beritra Air Raid: what to expect
Beritra Air Raid is the version most players search for, because its name sounds like a raid. It is not: it is the Balaur flavour of Dimensional Invasion. A Dredgion transporter lands, and the arena fills with Drakan infantry, Armed Air Raiders and packs of Air Raid Rovers, with Warmages and Destruction Engineers mixed in as elites.
Kill the casters first. Air Raid Warmages spawn in groups and hit hard from range, and the Destruction Engineers are elites worth more score than the basic soldiers. Rovers come in large packs, so they are the best target for area skills while the boss has not spawned yet.
When Air Raiders Captain Tetrata appears, switch to the boss and stay on it. Client data also lists extra Monolith rewards on some Beritra Air Raid rounds, with items such as Soul Codex: Reset or Hidden Cube Keys, but these do not appear every time.
Do not confuse it with Beritra Brigade Fortress, an instanced dungeon from the Korean version that is not open on Global servers.
Dimensional Invasion reward keys explained
The Dimensional Invasion Reward Key is what turns a normal clear into a good one. You get 1 key per day, it refills at 07:00 UTC with the daily reset, and you can store up to 7. The key is shared by all characters on the same server, so alts on that server do not get their own.
The key is not needed to enter. It is spent on the reward screen at the end of a clear, where it opens the key package on top of the regular rewards. Because the cap is 7, you lose nothing by playing a few days a week: just spend the stored keys before you hit 7, or the next daily key is wasted.
Players report that the top scorers in a round get more card picks than the rest, but NC has not published the exact rules for Global, so treat any rank table you see as unconfirmed.
Dimensional Invasion rewards: what a clear and a key pay
AION 2 Dimensional Invasion rewards at level 45+ (client data, November 2026)
| Reward | Regular clear | With a reward key |
|---|---|---|
| Centuryroot Tokens | 50 | Extra 30 (50%), 40 (30%), 60 (17%) or 100 (3%) |
| Enhance Stones | 700 | Extra 1,200 |
| Abyss Points | Some level 50 tables add 320 to 480 | Extra 800 |
| Soul Codex (Bound) | No | Yes |
| Other | Chance at gear, Refining Stones and crafting materials | Chance at Epic or Unique gear |
On average a key adds about 40 Centuryroot Tokens (our own math from the odds above), so one keyed clear is worth roughly 90 tokens and 1,900 Enhance Stones. Seven keyed clears a week add up to more than 13,000 Enhance Stones, which is a real chunk of your weekly enhancement budget. The Enhance Stones feed straight into the upgrades in our AION 2 gearing guide, and the Soul Codex goes into Soul Binding.
Centuryroot Tokens are spent at the Shugo Festival shop. One example: an Empathy Candy for a pet transformation costs 20 Centuryroot Tokens there, so a single keyed clear pays for several.
How to score higher in Dimensional Invasion
- Arrive early. Join during the gathering window so you are in position when the first wave lands.
- Open with area skills. Score counts damage and kills, and the early waves are packed together.
- Hit elites before trash. Warmages, Engineers and other elites are worth more than basic soldiers.
- Save cooldowns for the boss. The boss spawns in the center near the end and is the biggest single share of the score.
- Stay alive. Time spent dead is time not scoring; healers and support players still earn score by keeping the crowd fighting.
Damage still decides most of it, so a stronger character scores higher in the same arena. If you are behind, our AION 2 Combat Power guide shows where your next upgrade should go.
Is Dimensional Invasion worth doing every day?
For most level 45+ characters, yes, at least once a day with a key. It takes about a quarter of an hour, needs no group and pays Enhance Stones, Abyss Points and Soul Codex that you would otherwise grind in dungeons. Rounds without a key are worth it mainly for the 50 Centuryroot Tokens and the steady stream of Enhance Stones.
There are also achievements for it: the Dimension Defender series unlocks at 3, 10, 30, 60, 100 and 150 invasions, so regular players finish the lower tiers without trying.
