Merdelain | The Final Battle Neverwinter Nights 2 Guide
Last update: 11 May 2016
When you're back inside the Keep, it turns out that Aldanon is ready to open a portal that will take you directly under Shadow King's nose. This quest is to be done with all party members on board. After a while you'll be taken way behind enemy lines. Neeshka's been captured! That might complicate things if you're not a rogue yourself, but you can't really do anything about it.
HINT: Around this area your chances of successful resting are about 25% - in most cases enemies will interrupt it. In most cases it's really worth the risk.
Look around the area and grab some equipment if you like. Open the door leading North (1) and go through it. The whole area here is about defeating enemies and crossing misty portals in the right order: (2), (3), and (4). Eventually you'll reach a room where three shadow reavers await you for battle (5).
This battle is extremely difficult, especially that the tight path that you're on is a very uncomfortable spot to defend yourself. It's good to back off from it and take them on in a more open area. One of the reavers will actually teleport behind your back, so try to take him out first. As usual, the key is reciting their true names - be sure that both Ammon and Zhjaeve are safe, as without them you're doomed. When you manage to defeat the enemies, the only thing left is the grand finale.
