Aion 2 patch notes: Krao Cave and Draupnir Hard mode, the Ariel board

What changes for farming and trading

• Hard mode can drop Philosopher's Stone: Revelation (Bound), which can also be picked as a guaranteed reward, plus Expedition Hero Artwork and Ariel Fragments (how many depends on the dungeon).
• Hard mode pays more Kinah than Normal mode. The notes don't say how much more.
• Krao Cave and Draupnir get a Hard mode. You need item level 2,600 to enter, bosses enrage after 4 minutes, and each player has 3 revives.
• Some players whose trading was restricted can trade normally again; the restriction stays for others.
• Every Unique crafting material drops in Hard mode, Wrathful Mind, Wrathful Will and Wrathful Ego among them.
• New Expedition (Hard) achievements reward Unique skins.
