iv tested out somethings on conan exiles , and dont mind my english
If you build a box with 1 fundation 3 walls 1 doorway , a pillar in the middle and a door, you can get damaged by anyplayer or npc if you stand next to that pillar. i did a test where i placed 1 pillar and a fundation right next to it, i had my explosive next to the pillar and the fundation behind didnt take any damage from the explosion even tho it was veryclose. and vit perk 50 isent working, i get the same health back from food if i have vit perk 40 and 50.
