PvP & combat
Where fighting happens
Wilderness: PvP is always on.
Claims: PvP is off. You are safe there – unless you are in combat.
No escaping: if you got into a fight in the wilderness, you can still be attacked on a claim and fight back until combat ends.
Whoever stands on a claim and is not in combat can neither attack nor be attacked.
In combat
Whoever hits or gets hit is in combat for 15 seconds.
Then you can't teleport or create a claim.
If you log out in combat, you die. Your items drop on the ground.
