Water wells and oil pumps should be open for everyone to use, these shall not be blocked. There's a limited supply of these resources on the map.
It is not allowed to build water wells on water veins that are not connected to your base as this basically makes it impossible for anyone else to build in that area.
Wyvern milk cages are only built by admins, this is to prevent the map being flooded by cages. Same goes for griffin cages.
We wish you a warm welcome to ARKNordic.se - PVE, Ragnarok
