This a rather large settlement and has a lot of treasures to loot. Some of the chests are located on the rooftops while the others are along the narrow corridors at ground level so take your time exploring the area. After collecting the treasure, make your way to the temple door. Before going inside, make sure you have ample amount of curatives and your party donning the best equipment you can get since there's a boss battle ahead.
Note: There will be no enemies during your first visit in the area. But if you happen to enter the Bitterblack Sanctum, leave and return, expect heavy resistance before you can reach the Sanctum. You may want to stay on the rooftops to avoid getting pummeled by enemies in the narrow streets or even get trapped by enemy spells.
Expect even heavier and deadlier myriad of enemies in the area once you return after defeating the labyrinth’s last boss. The area will be patrolled by living armors, thunderwyverns or eliminators. You may even face Death at the same time. If you don’t want to bother with them, you can just scale the rooftops and run towards the Bitterblack Sanctum entrance.
