Conan Exiles -Volcano Purge with minimal lava

Here's one way to do it controlling the purge with building style. No doors, no thralls, just a small maze, arrows and a thin strip of lava. Not a well produced video, just wanted to share what is possible.
Also shows a "bug", where the server plants a purge camp then during the first wave decides it's too far ... go figure, you'd think it would have mathed that out before placing the camp.
Edited for time.
