Disclaimer: Translation is hard! Some of these notes, especially more complex ones, may be slightly off. We'll post the official English notes when they're posted as well.
Update! Warbringer change clarified (again). Ghostcrawler chimed in about it.
Dungeons and Raids
- The Frostwing Halls, the last stronghold of the Lich King and the Scourge, has been added, but the Ashen Verdict must break down the door first. (Does this mean we have to wait some additional time to fight Arthas?)
- Brann Bronzebeard has been working out, so he'll run faster during the escort event.
- Devourer of Souls will cast Mirrored Soul less often.
- Trash mob Spell Reflect abilities have been changed. It now has a casting time, and will proc only twice at a rate of 75% instead of 100%.
- Anomalus will create rifts only once.
- Elder Nadox's Ahn'kahar Guardian will only spawn once.
- Jedoga Shadowseeker will initiate her volunteer phase only once.
- Some trash packs between Nadox and Jedoga have been reduced/removed.
- Dead players are now able to re-enter the instance when the Ick/Krick and Forgemaster Garfrost encounters are active.
- Players can bring down Skadi's drake using only three harpoons, down from five.
