I've just finished the new solo instance of Arah's story mode on an alt account. Some things to note:
- You can only complete Arah's story mode at the end of Victory or Death once per character. (If you want play through it a second time you'll need to use a different character or hitch a ride with another player)
- The 5 player instance has been removed from game.
- The difficulty level of the instance is low: somewhere between personal story and living world.
- Completing the dungeon will unlock the Arah PvP reward track.
- Completing the instance at Fort Trinity will reward a bonus piece of Arah gear.
- "Press 2 to kill dragon" has been changed to "Press 1 to kill dragon"
