Fornost: Destroy the War Machines
There are some crates and barrels in front of and behind you. If you didn't find the Westernesse Artifact in the previous level, then now - in one of the barrels or crates - you'll find it for sure ([SIDE QUEST] Work of Westernesse). Keep destroying everything you can on the way till you get to your first enemies.
You will meet a goblin sorcerer for the first time. There are also several warriors here and a lot of goblins, however, deal with the archers in front of you first. Locate a red ball - if you shoot at this explosive the enemy archers will be gone.
After that quickly take care of the sorcerer. He throws the dangerous fireballs and their explosions can knock you down and wound seriously. Yet, it's not a tough enemy. Flood him with blows, which will prevent him from casting a spell.
It's necessary to take the items that will fall out of his body. Among them you'll find the Malignant Scroll. Once you pick it up, a [SIDE QUEST] Cult of the Lidless Eye will be started. The scroll is also the [SECRET 1/1 for everyone]. Finish off ordinary goblins and warriors. You will not have any trouble here, though new goblins will be joining the fight.
Destroy all the crates and barrels around, and then move closer to the war machine and begin to quickly press the use/inspect button. You'll push it down this way - the other will remain. Cross the wooden bridge.
There are several warriors and another sorcerer hiding behind the corner. On top of all that the area will be teeming with ordinary goblins. Try to kill the sorcerer using melee or a ranged weapon before you get surrounded, and then deal with the rest of the enemies. Fight until there is nobody else here except the three of your characters.
On the left there is a chest and on the right a heap of items (search both). There are a lot of barrels and crates around and opposite - the second war machine you should push down now. You will receive a new objective of the quest. Head for the gate nearby and destroy all crates and barrels. Pass through the gate when it opens and use the glowing portal so that the game will be saved automatically. Destroy a barrel and a crate and then bring the view closer on a group of goblins who are standing on the other side of the bridge, on an elevation.
Fornost: Make your way to the end of the battlements
Approach the wooden bridge, but don't go further. You will receive three Great Feathers, which will make it possible to summon Beleram. Enter the aiming mode, zoom in, place the crosshair on the sorcerer and press a suitable button. Beleram will literally drop from the sky and neutralize the enemy at once. The fight with remaining goblins will be much easier due to that. It's also worth knowing that if you call the great eagle 10 times during the game, you will unlock the [ACHIEVEMENT] Swift-winged Warrior. However, we suggest leaving his help to use when you deal with really burdensome or powerful enemies.
Run on the bridge and begin to fight the warriors. Archers will be shooting at you the whole time but warriors should cover you. Finish off the former once you are able to cross the bridge.
The last enemies are two warriors who will come through the abovementioned gate. You will defeat them without a problem. Then all that's left to do here is searching the place thoroughly. Downstairs and upstairs there are some barrels and crates. Additionally, there's a chest to be searched downstairs. Head for the glowing portal to finish this level after you've taken all the items.
