One-way maze (sky box fit)

Did you know that Charred banner can be used as a one-way door?

Prefab name is Charredbanner3 and it's actually not used in the game. It looks like a normal banner we can build as decoration, but with charred symbols. It will let you go through it from back, but will block you from front side. Back and front side are not exactly the same (back side has holes in it) which makes it prefect for a maze like this.

I showcased it in this build.
The maze is made in Infested mines skybox, but can be placed on the ground if you prefer it that way. Just make sure to flatten 64x64 meters area.

The maze has 13 containers with loot, including level 6 fenris armor set (not all the pieces are in the same container), level 99 building hammer, indestructible cultivator, indestructible torch and other loot with mistlands materials. All the containers are marked with dverger pole lantern so you can change the loot to your likes.
The entrance, which is also the exit is marked with fying core (big pink glowing gem) to make it easier to find your way out once you get lost (and you will).
Lanterns and glowing core won't help a lot if you place the build outside and play during the day, so you might want to change that with something that is easier to see during the day.

Step by step instruction for the sky box version:
1. Find a place with low instance count, preferably a small mistlands island and spawn a dungeon
spawn_location Mistlands_DvergrTownEntrance1 pos=0,0,0  - this will spawn Infested mines entrance in front of your character. There are two version of entrance (1-tower version,2-stairways into the rock version)
2. Remove the dungeon from inside using planbuild tools.
3. Select a blueprint and aim at the bottom of the dungeon entrance (white box) and place it
4. Make sure to select Unlimited health when placing blueprint because banners are easy to break and we don't want that to happen.
5. That's it. Everything is ready.

Optional: spawn some enemies in several rooms - they won't go through banners.
