Last update: 21 September 2023
Immediately after completing the task Wake Up Art Cullagh's, you will receive the quest Lift The Shadow Curse. You'll learn how to lift the curse and recruit Halsin - you must complete this quest, or he won't join the party and will leave in act 3.
How to prepare for the portal defense?
Take a long rest and head to the lake, where Halsin is waiting. Have a Cleric in your party, such as Shadowheart - they'll come in handy in the upcoming fight.
How to defend the portal with Halsin?
Talk to Halsin and prepare for battle - you must defend the portal for four turns. The enemies attack in waves, but there's only one way to the portal - through your party. Have your Cleric cast Spirit Guardians and choose Radiant damage - it will be invaluable in this fight.
Place the Cleric in the middle of the path towards the portal and cast Spirit Guardians. As pictured above, warriors and archers spawn in the top left corner - use AoE spells to deal with them, such as Fireball, Wall of Fire or Glyph of Warding.
After the battle, watch the cutscene. Collect the staggering amount of loot dropped by the defeated enemies. Return to camp and talk to Halsin.
After talking with Halsin, you can finally add him to the party. Now you can start searching for Thaniel's second half. Head to the location pictured below - coordinates X:61 Y:22.
How to defeat Oliver?
Enter the house and talk to the child.
If Halsin's in the party, he'll tell you that's the child you're looking for. Tell him you know who he is, then chase him through the portal.
You'll face Oliver in the central square. Your goal is to destroy the barrier that defends it. This is done by defeating enemies - focus entirely on them.
After the fight is over, persuade the child to unite with Thanial. Return to camp and talk to Halsin. Thaniel will explain there's one last thing he needs to lift the curse - the death of Ketheric Thorm.
