Invasion Boss in Altgard
Beritra's Grand Invasion is one of the main features introduced in 4.7. During a specific time of the day, special world bosses spawn in one or more areas, awarding its killers with unique loot. An invasion may take place in every zone, with the exception of starting areas (Poeta/Ishalgen), main cities (Sanctum/Pandaemonium) and housing zones (Oriel/Pernon). If they are not defeated by the hour of their spawning, they will disappear.
Backstory[]
After finding and activating the Hyperion, the Danuar weapon, Beritra gained valuable knowledge of Ide. Although the weapon is now in ruins by the hands of Daevas, it has not stopped the Dragon Lord from finding ways to use Ide for building massive war machines for his latest plans.
Aion Cutscenes - Beritra's Invasion
Along with the information about teleportation devices acquired from the Linkgate Foundry, Beritra managed to launch a full offence on not only Balaurea, but Elysea and Asmodae alike. Initial sightings of these attacks took place in Danaria by Shugos and guards. According to them, these dangerous weapons appeared all of a sudden and disappeared the same way. Daveas were dispatched to investigate these events, resulting in a great worry for them. In response to the imminent threat, Daevas were sent to destroy them as they popped.
Although considered just a sheer force attack, Beritra's plan had more sinister motives. With these constant attacks, the Balaur desired the complete destruction of several Balaurean zones; Sarpan, Tiamaranta, Katalam and Danaria. With these areas destroyed, these lands would be swallowed by the abyssal sea and the hidden continent would rise revealing the seal created by Tiamat to hold a special power wished by Beritra.
Mechanics[]
Between 7:30 and 9:00 pm (CST) from the 1st to the 28th day of the month level 65 bosses may spawn in their designated areas, following the next pattern: Levinshor, Kaldor, Cygnea, Levinshor, Kaldor, Enshar. Lower level invasions follow a similar way, however the one has not been defined yet. Every month, on the 11th day, all bosses in all its locations will spawn at 9 pm (CST).
There are different types bosses and different strategies to take them down. For each boss, there are three grades (Grade I, Grade II and Grade III). When the boss is defeated, the group/alliance which gets the prize will be able to loot the boss for a bundle which will give the player different prizes. Grade I offers the best prizes, which includes pieces of the Betrayer set (either Superb or Fine), potions, Idians and purification supplies. While Grade III will only drop potions and idians. Additionally, mythic gear pieces from Illuminary Obelisk and Danuar Reliquiary may be obtained from the bundle. Furthermore, higher the grade, higher its difficulty.
When a player gets near enough a boss, the Game Time shown will instantly change to Night, which also affect the background lighting and music. Once killed or despawned, it will revert back to their respective state. Furthermore, when looting these bosses, multiple players will be able to loot it at the same time.
