How to start focus on the mountain fortress in Gothic 1 Remake
The Focus at the Mountain Fortress becomes available during The Focus Stones, a main quest Saturas gives you after completing The Water Mages' Plan. Before going after any of the focus stones, you should first visit the tower that Diego marked on your map when he gave you The Water Mages' Plan.
When you reach that tower, talk to the NPCs there to mark the positions of the focus stones on your in-game map. This conversation also causes the accompanying NPCs to move to their assigned focus stone locations.
Where to find the mountain fortress
The mountain fortress is located southeast of the Old Camp. If you visited Diego's marked tower before heading out, the focus stone location should already be marked on your in-game map. However, you can use the map above to find the fortress if needed.
As you approach the mountain fortress, you'll find Lester waiting just before a bridge leading towards it. Talk to him to get a warning about the golem ahead.
There are dangerous enemies in and around the mountain fortress, including harpies. Make sure you have some healing items on hand and save manually before attempting to cross the bridge.
How to beat the Golem on the bridge
Lester will warn you that the golem blocking the bridge can only be damaged with a blunt weapon, and you should equip something like a mace or club if you have one handy. Don't worry if you don't have access to a blunt weapon, as you can still get through the fight by letting Lester do most of the work.
In fact, Lester's mace can damage the golem, and it doesn't take too long to bring it down. Just focus on keeping the golem occupied and alive, and let Lester handle the crime. Once the golem is defeated, continue across the bridge and follow the winding path up towards the mountain fortress, dispatching the Harpies along the way.
How to reach the Mountain Fortress Library
After entering the mountain fortress, go forward and pass through the first door on the right. Go up the stairs and then pass through the opening on the right to reach an outer walkway. Follow that walkway, re-enter the fortress through the opening on the left and continue up the stairs.
You will soon come to a room with a headless marble statue and paintings on the wall. Continue into the next room, which is a dining room, and pay close attention to the large painting on the wall. It gives you the solution to the bookshelf puzzle in the library in front of you.
How to solve the Mountain Fortress Bookshelf Puzzle
The large painting in the dining room shows a sea creature eating a wolf, and the wolf eating a Molerat. This sequence provides the solution to the bookshelf puzzle in the library, as it involves interacting with the bookshelves in the correct order. Each bookshelf has a creature statue on top of it, and you should interact with them in the order shown in the painting:
- Sea animal bookshelf
- Wolf bookshelf
- Painted bookcase
After interacting with the bookshelves in that order, the hidden door in the corner will open. Crouch through the opening, go up the stairs on the right and follow the path to a ladder used to reach the attic. From there, drop off the edge of the attic into the room below.
Where to find the locked chest in the mountain fortress
After dropping from the attic, turn around. The door behind you leads to a locked chest, and although you can complete Focus on the Mountain Fortress without opening it, the chest contains a suit of Royal Guard Armor. To claim the wearable, you must track the chest key.
You can only reach the location of the chest key if you have learned how to climb walls. You can train that ability as part of Aiming High, a side quest that comes from Theron in Swamp Camp, and you should ignore the Mountain Fortress locked chest if you don't have it.
Where to find the locked chest key in the mountain fortress
To find the key to the locked chest, start in the room you entered from the attic. Go through the door across the room, go up the stairs and continue to the end, where you'll find an opening in the wall.
If you have learned to climb walls, you will be prompted to wall climb when you approach the edge of that opening. Press the entrance that appears and climb up and to the left to find another opening. Pass through that opening, go right and climb the stairs to reach an inner area with a couple of Harpies.
After defeating these enemies, use the outer walkway with stairs to continue moving upwards. The chest containing the locked chest key is at the top of the stairs, near more Harpies, and you must pick its lock. For more information on lockpicking, see our How to Lockpick guide.
If you really struggle with your chest, use this lockpick solver. Since lock solutions vary depending on your lock picking training, it is difficult to provide a universal sequence, which is why a specific one is not offered here.
How to get Royal Guard Armor
After looting the key from the chest at the top of the tower, climb back down the wall and return to the locked chest in the room below the attic. Use the key to open the chest and retrieve the Royal Guard Armor inside.
Again, this armor is not required to complete The Focus at the Mountain Fortress, and you shouldn't worry if you don't have the ability to climb walls and can't get it. But if you can climb walls, you might as well grab the Royal Guard Armor while you're at the mountain fortress.
How to find the focus stone at the mountain fortress
After opening the locked chest or deciding to skip it, go back to the room you fell into from the attic and go to the opening in the wall. Look down and to the right to see the focus stone below, then climb down to it. Now defeat the harpies that appear and interact with the stone to receive the focus from the mountain fortress.
How to return to Lester
After collecting the focus from the mountain fortress, climb back up towards the opening you passed earlier. About halfway up, look to the right and drop down onto an outer walkway that wraps around the tower.
This is the same outer walkway you used when you first entered the fortress. Follow it back along the route you took earlier to return to the room with the bookcase puzzle, where Lester should still be waiting.
How to complete focus on the mountain fortress
After speaking with Lester, you can leave the mountain fortress and return to Saturas when you are ready. Turning focus in from the mountain fortress ends the mission and advances the Focus Stones.
