Old blessings system (Amulet of Loss and 5 blessings from NPCs).

On our server, we put fun first. We do not tolerate random PK.
PvP rules are stricter for this reason.

In PvP worlds you can attack any player (with exception on Rookgaard).
This will give you a White Skull, and if you kill someone you will get a protection-zone lock for 15 minutes and your skull will stay during that time.
If you kill a player without a skull, you will gain a frag, and depending on amount of frags, you may recieve a Red Skull or even get auto banished.
You do not gain frags from killing players wearing skulls.
If you would recieve a Red Skull, it will be lasting for 30 days from the last moment you had frags enough for a Red Skull.
A Red Skull always drop all items upon death, so if you have a Red Skull, be extra careful.

If you would recieve a Auto Banishment, it will be lasting for 30 days!
