Abyss Boss Encounter Mechanics & Tactics

1. Guardian General Nahma (Eye of Reshanta)

Spawning exclusively on Friday and Sunday at 21:00 server time, Nahma represents the highest tier of PvPvE combat in AION 2. The encounter takes place at the heart of Reshanta where both Elyos and Asmodian alliances can engage simultaneously.

Wrath of the Aether (At 50% HP): Nahma casts a lethal 360-degree aetheric blast wiping anyone outside barrier wards. Templars must trigger group shields.
Faction Tagging: The alliance dealing the highest cumulative damage receives priority mythic loot chests, making PvP disruption of enemy DPS parties critical.

2. Fortress Siege Bosses: Tamasa, Argo & Kaira

Triggered immediately after fortress gates fall on Monday, Wednesday, and Saturday at 21:30 server time. These commanders require rapid tank swaps and high burst single-target execution before fortress vulnerability windows close.
