What are the Skulls?
The Skull System is a system that was made to make sure that Player Killing wouldn’t get out of control. When a player attacks someone who is not skulled, he/she gets a white skull. If a player kills someone with a white, red, yellow, black or green skull they won’t get skulled.
Kill a NPC counts as a frag. You can drop your loot when you are marked with a skull, but you can use the Amulet of the Gods for prevent this. Also, stay tuned about the Hand button (): when the hand is closed (), you can attack any player, but you cannot enable/disable it if you are infight.
When you are not skulled and you die, you have a chance of 15% of drop your backpack and a chance for each item equipped of 10% to drop it. Also, the time to decrease each frag is 12 hours.
