Diff - strongholds and sealed dungeons - AION 2 Wiki

1-Strongholds and Sealed Dungeons are the two kinds of small, repeatable instance spread across each AION 2 territory. Strongholds are enemy camps: Balaur outposts and patrol bases, bandit dens and renegade hideouts. Sealed Dungeons are hidden caves, ruins, libraries and lairs. Both are part of the field layer of Verteron, Altgard, Eltnen and Morheim, alongside the Monoliths and Empyrean Traces and the Field Bosses.

1+Strongholds and Sealed Dungeons are the two kinds of small instance spread across each AION 2 territory, found by exploring and cleared once per character. Strongholds are enemy camps: Balaur outposts and patrol bases, bandit dens and renegade hideouts. Sealed Dungeons are hidden caves, ruins, libraries and lairs. Both are part of the field layer of Verteron, Altgard, Eltnen and Morheim, alongside the Monoliths and Empyrean Traces and the Field Bosses.

33 NCsoft's English press release for Chapter 1. Lands of Sand and Snow describes Sealed Dungeons, Strongholds and Monoliths as the places where players earn the rewards needed for progression, and its June 17, 2026 announcement listed 20 new Sealed Dungeons and six new Strongholds across Eltnen and Morheim.

5+Finding and Clearing Them

7+The official guidebook calls both exploration content: they are found by exploring the world and cleared on discovery. They are placed all over the world map, and following the question mark markers on the map leads to their entrances. Each one is a one-time clear for a character; the Korean Daeva Express tickets work by clearing every one a character has not yet cleared, and player guides confirm that a cleared Stronghold cannot be entered again.

10+Clears also fill the Daeva Gauge toward the next Ascension quest; see Journal. Player guides add two tips: each Stronghold holds three chests worth collecting before you leave (decline the automatic exit prompt to pick them up), and you can drop into a Stronghold from the air instead of using its door.

714 The Korean service changed how these instances pay on December 3, 2025: monster drops inside them were removed, and every clear of a Sealed Dungeon or Stronghold pays 15,000 Kina instead. From December 17, 2025 the Silentium they drop is bound to the character. From December 24, 2025 the item drop limit that applies once a player reaches the daily Kina allowance was extended to cover them as well.

1623 With Chapter 1 the Korean build added Daeva Express tickets for Strongholds and Sealed Dungeons. Using one clears every Stronghold or Sealed Dungeon the character has not yet cleared in the chosen territory and grants the rewards. The paid Exciting First Step package announced alongside Chapter 1 does the same for Strongholds, Sealed Dungeons and Empyrean Traces at once. The Transparent Map overlay added on July 22, 2026 works inside Sealed Dungeons too.

On August 12, 2026 NCsoft completed the achievements that Sealed Dungeon Express tickets used between July 1 and July 15 had failed to register, and re-issued tickets to players who had converted Quna-bought tickets into 5,000 Enhancement Stones.

1828 Verteron Strongholds

1929

2030 Verteron has 15 Strongholds. The Korean build's Spacetime Rift: Domination mode launched on September 2, 2026 with them split into three groups of five, one group opening at random each time the event runs. The September 9, 2026 update cut each group to four, and the three Strongholds marked as removed below left the rotation. The names come from the game's English client data as of September 18, 2026 and are provisional until NCsoft uses them in an announcement.
