Diff - abyss bosses - AION 2 Wiki

11 Abyss bosses are the named bosses of the lower and middle layers of the Abyss. Some respawn on their own timers, the Guardian Lord Nahma bosses appear on fixed evenings, and six more arrive in a boss event that follows each artifact battle. Both factions fight over them, so every one of them is also a PvP objective. The English names on this page are the global game client's; NCsoft's English announcement of Season 2 also used Guardian Lord Nahma. Everything here describes the Korean and Taiwanese service: as of October 7, 2026, NCsoft has not published Abyss boss schedules for the global servers.

33 Boss List

55 Levels and locations come from the global client's data. The game labels the two layers Chaotic Lower Reshanta and Chaotic Middle Reshanta; times are Korean time.

1010 Guardian Lord Nahma

1111

1212 At launch a single Guardian Lord Nahma appeared in the lower layer. With Season 2 on January 21, 2026 the lower layer received three, and the reopened middle layer received up to two Enraged Guardian Lord Nahma. The schedule has moved several times:

1515 A fault kept Guardian Lord Nahma from spawning properly on some servers between November 23 and December 13, 2025; NCsoft later sent eligible characters a rare Nahma merit box as compensation. On May 27, 2026 both Nahma bosses received about one and a half times their HP.

1717 Watcher Kaira and Argo, the Spirit King

1818

1919 Watcher Kaira and Argo, the Spirit King are the lower layer's own field bosses. In December 2025 Watcher Kaira was listed with a one-hour respawn cycle and a spawn chance rather than a guaranteed spawn, and Argo with a 24-hour respawn. On September 2, 2026 Kaira's spawn chance went from 20% to 100%, on a four-hour cycle; a temporary maintenance on September 4 moved the start of the cycle from midnight to 01:00. Each spawn picks a random point, with no difference in odds between points. Both bosses had their HP raised about threefold on May 27, 2026.

2020

2121 Since December 17, 2025 the Kina one character can collect from a boss kill has been capped: 1,000,000 Kina from Guardian Lord Nahma, and 200,000 Kina each from Watcher Kaira and Argo, the Spirit King.

2323 The Boss Event After the Artifact Battle

2424

2525 Since April 22, 2026 a boss event follows each artifact battle in both layers. When it launched it started at 10:30 PM on Wednesdays and Saturdays, 5 to 10 minutes later for some matching groups, and brought Watcher Kaira, Argo, the Spirit King and Executor Tamasa to the lower layer and Executioner Dramos, Turncoat Ducal and Ravager Marakha to the middle layer. The ordinary Watcher Kaira and Argo kept their own spawn schedules. On April 29, 2026 the event versions were renamed Executor Kaira and Executor Argo so they could be told apart from the field bosses of the same name, and the three lower-layer event bosses had their stats raised. Their HP went up by about one and a half times on May 27, 2026.

2626

27-Since September 30, 2026 the event bosses appear at 9:45 PM for matching group 1, 10:15 PM for group 2 and 10:45 PM for group 3, still on Wednesdays and Saturdays.

27+The September 30, 2026 schedule placed the event bosses in three time groups: 9:45 PM, 10:15 PM and 10:45 PM on Wednesdays and Saturdays. The October 7 rematch assigns the 21 matching groups to those three time slots as follows; all times are Korean local time.

2930 Rewards

3031

3132 Rewards are paid by contribution. Since July 1, 2026 they follow contribution rankings per class rather than one overall ranking, so more players are rewarded.A player who dies during the fight is still rewarded by contribution while within the 100 m reward range of the boss.PvP counts: since May 13, 2026 the players who damaged an enemy killed near a boss gain contribution on that boss, and since May 20, 2026 dealing damage or healing allies in PvP near a boss builds contribution in real time. The September 2, 2026 update raised the contribution that PvP earns again.The Nahma bosses give materials that convert into Nahma merit boxes. The event bosses give materials that convert into Dimensional Merit Boxes and Superior Dimensional Merit Boxes (April 22, 2026). All of these boxes can contain Abyss Potential Amplification Stones, and their merit medal contents have been raised several times, most recently on September 16, 2026.Since April 29, 2026 Executor Tamasa, Executioner Dramos, Turncoat Ducal and Ravager Marakha can drop a painting of themselves.The global client's drop tables also list Artwork items, refining stones and Unique-grade boss equipment, such as the Guardian Lord Nahma Breastplate and Greaves and the Argo and Kaira Breastplates.

3334 Fight Rules

3435

3536 Abyss field bosses leave the field 30 minutes after they appear (since April 22, 2026).Since September 23, 2026 every player on the map receives a battlefield buff (전장의 권능; no official English name yet) while any of these bosses, or a Dimensional Core, is up in the lower or middle layer. It replaces seven class buffs while active, among them Experienced Counterstrike, Fury, Undefeated Mantra, Light of Protection and Power of the Storm, and ends when no boss is left on the map.A debuff called Decline of Power (힘의 쇠락; literal translation) lowers a boss's damage resistance and resistance to Double Chance once a fight drags on. A temporary maintenance on September 23, 2026 made it start after eight minutes instead of ten for lower and middle layer bosses, and the September 30 update fixed it not applying to Enraged Guardian Lord Nahma.The HP of Abyss bosses and Dimensional Cores was raised on September 23, 2026, when PvP damage amplification started to apply to Monoliths and guards in the Abyss.
