Codex Barrier – Ylands

When starting a new Exploration game, you are equipped with a damaged Protective Barrier Generator.

• Once you find a way of fixing it (via crafting) you can place it in the world and you will be able to see a line marking what will be inside the barrier when you turn it on.
• Once you (only you can operate your generator) turn the generator on for the very first time, it will anchor itself and you will not be able to remove it even after disabling - so choose the location wisely.
• Barrier is invincible and can’t be destroyed by Annihilator or other tools.

When the generator is turned on the barrier becomes active. Inside of it:

• Terrain can't be modified by other players
• No energy streams can be started/removed by other players
• If you leave your character there when logging out, they won't receive any damage from other players or animals
• You can use any kind of hammer to instantly deconstruct man-made objects there (allowing you to easily rebuild your house etc.)
• Objects that are placed into grid by default can't be placed there by other players in any way
• No objects can be directly damaged by other players

But keep in mind, that it does NOT prevent others from entering/hurting you (when you're online)/stealing your property!
