AION 2 Expedition Hard Mode: Krao Cave and Draupnir

AION 2 Expedition Hard mode comes to Krao Cave and Draupnir with the 21 October 2026 (CEST) patch, with entry at item level 2600, a 4-minute boss Frenzy timer and 3 revives per player, according to the NCSOFT patch notes on Steam. Below is an overview of the published requirements and rewards; we have not run Hard mode in the client yet.

Hard mode is added to Krao Cave and Draupnir. Required item level for entry is 2600, a high entry bar for the mode.

Two limits define the mode: the boss Frenzy timer is set to 4 minutes, and each player is limited to 3 revives. The patch notes name both limits but do not describe what Frenzy does when the timer ends.

The patch notes list the Hard rewards below. Chances are stated as chances only; no percentages are given.

Crafting materials: what the notes cover

The notes say all Unique crafting materials become obtainable from these two dungeons in Hard mode. Which dungeon drops which material is not stated.

Achievements and Unique Skins

Two achievement sets are added: Expedition Hero Artwork Collector and the Expedition (Hard) set. Unique Skins come from completing the Expedition (Hard) achievements.

The patch also adds a new Ariel Daevanion board. Ariel Daevanion Points are earned by collecting Ariel Fragments from Expedition (Hard) and morphing them through Substance Morph. So the points come from morphing, not from the fragments sitting in your bag.

On top of that, the number obtainable through Substance Morph is limited for each dungeon. The cap itself is a number the patch notes do not give.

Crystals: capped, and tied to the board

Our reading: the crystal route is the one the notes connect to the board, since crystals and board points appear in the same section of the notes. It is also the capped route, at 30 per character.

Enhance Stones: uncapped, but a different use

One fragment yields 5 stones with no limit, so 100 fragments would yield 500 stones, against a single crystal for the same 100. Our reading: stones look like the outlet for fragments you cannot put toward the board, for example after the crystal cap or the per-dungeon limit. The notes do not say what the stones are used for or what a board point buys.

Time cost: filling the crystal cap on one character means 30 x 100 = 3,000 Ariel Fragments (arithmetic from the notes’ numbers). How many clears that takes cannot be calculated, because fragments per clear are not published, and the per-dungeon limit may stop you earlier.

Reaching item level 2600

No NCSOFT post checked gives a route to 2600; the official line is only the entry requirement. The practical starting point is level 45, which is when Duties unlock; see AION 2 level 45 Duties and the tab bug. For gear and stigma choices on your class, see AION 2 class builds from the official Armory. The Armory shows your Item Level, so check it before queuing.

Revives: the Rise to the Challenge event

Because Hard mode caps revives at 3 per player, the event is relevant. During it, Resurrection Spiritstones (Season 1) are sold for Kina under Shop > Wind Breeze Merchants. The event runs until the start of maintenance on 15 December 2026 (PDT/PST) or 16 December 2026 (CEST/CET), per the official event post.

Buying both steps once adds up to 75,000 Kina for 60 stones (arithmetic from the two rows).

The event post says only that a stone is used “upon resurrecting a character”; whether it works on another fallen player is not stated, so read the in-game tooltip.

Conditions from the event post:

• Order: Step 2 opens only after you reach the Step 1 purchase limit.
• Removal: the event stones are time-limited and are removed on 16 December 2026 at 00:00 PST / 09:00 CET.
• Use order: time-limited stones are consumed before any permanent Resurrection Spiritstones (Bound) you already hold.
• Trading: all event items are non-tradable.

The notes we read do not give drop rates for Philosopher’s Stone: Revelation or Expedition Hero Artwork, the number of Ariel Fragments per clear, the per-dungeon Substance Morph cap, or the Ariel board’s nodes, bonuses and costs. We have not checked these in-game. Whether Spiritstone use counts toward the 3-revive limit is also not stated.

We have not run Hard mode in the client, so these are not checked either:

• the interface path to Hard mode;
• how Krao Cave and Draupnir differ on Hard;
• boss mechanics, including what Frenzy does;
• how revives are spent and counted;
• the reward-selection screen and the crystal screen in Substance Morph.
