Where does boss loot come from?

Dungeon bosses drop their loot inside the dungeon: each dungeon page shows the loot table for every mode and, where the client records it, which boss drops which item. Challenge tiers pay fixed rewards instead.

Data read from the AION 2 global client (build 0.0.4387.0). Updated for the Nov 4, 2026 patch. How we read the game files

AION 2 has 58 bosses in the global client, from level 45 to 86. Most are fought inside dungeons, and 26 of them also have a boss challenge ladder where each tier asks for more combat power and pays out bigger first-clear rewards. Each boss page lists its dungeons, every challenge tier with its rewards and similar bosses. Boss HP and mechanics are not in the client files, so we do not guess at them.
