Data read from the AION 2 global client (build 0.0.4387.0). How we read the game files
Ultimate Berk is a level 45 Hero enemy in AION 2 with no open-world spawn in the global client, so it is met in instanced content such as dungeons or events. Drop chances and challenge rewards come straight from the game's reward tables. Monster HP and combat stats are kept on the game server and are not in the client files, so they are not listed here.
Help us maintain accuracy! If you notice incorrect stats, missing data, or any issues, your feedback directly improves the quality of our data for the entire community.
Ultimate Berk appears in Krao Cave.
Its most common drops are Soul Codex (Bound) (100%), Refining Stone (100%), Silentium (Bound) (100%), and Kina (Bound) (100%). For Balaur's Essence (30%) you need about 7 kills for a 90% chance; the drop table lists every item.
Ultimate Berk is level 22–70 (Hero).
Yes. Ultimate Berk goes berserk after 5:00 of combat, so plan your damage to finish before then.

Yes. Roar of Fury: Stun (2s), Wave of Fury: Stun (3s), Extinction for Eternity: Stun (3s), and Chroma Storm: Knockdown (2s).
The AION 2 client does not contain monster HP or combat stats – they live on the game server – so no database built from game files can show real values. Level, rank, spawns and drops on this page come from the client.
