What it takes to stop the Taken

A Fence. The Taken can smash walls, bomb doors and boulders and use magic items to get through seals.

But we see in Homestead: The Taken can destroy fences, but still can’t get through them, not even with teleport or leaping runes.

So the Bloodsworn just have to put a fence in front of the Logghorrean Boss Door and all their problems are solved.
