This area has holy beacons that you can light up at a cost of some rift crystals to illuminate the area and weaken the enemies. It will make your job easier so light up the beacons you find along the way. There's also a secret compartment to the east of the beacon, behind some destructible crates.
The shortcut to the exit is due northwest but if you want to take the long path, take the path southwest. Make your way to the northernmost part of the map to find more chests along the way. When ready, exit the area.
