THE FINAL SEAL
Congratulations! You have reached the last level but one of Watcher's Keep. Your job on this level is to open the final seal. But to do that, you'll have to open three partial seals first. And to open them, you'll have to acquire some keys by passing some tests.
Also, when you open the seals you will be attacked by some very high-level enemies!

Before opening the seal, prepare for one of the hardest battles in Baldur's Gate 2. You will have to fight a Succubus named Nalmissra, a Marileth named Y'tossi, a Hive Mother, Xei Win Too who can use Kai and Greater Whirlwind attacks, a Drow Cleric named Ameralis Zauviir, and a demonic Ranger called The Huntress with the Called Shot ability.
Here you are met by a Helmite Ghost who explains to you that you need to complete some tests. Accept.
Once all monsters are destroyed, click the altar. If you have already done the Test of Bravery, you should have the Warrior's Skull. Your mind is transferred to a Spirit Warrior. Follow these steps to solve the maze:
