Important, before 4 reset, death penalties do not apply. At events other than attacking CryWolf, penalties do not apply.
If your character dies, you may be subject to penalties, the only way to avoid them is to have them with you (in the character's backpack) "An Apple" 
.There are no death penalties at events, with the exception of the CryWolf attack.
If your character dies from both monsters and humans, you lose 1 Fruit Points of each type (More in the section Fruit System). In addition, any thing dressed on you, including wings and pets, can fall out from you. And there is also a small chance that it will be completely destroyed.
Killing other characters has a number of restrictions, you cannot attack anyone and you also cannot be attacked until reaching 4 rebirths (Reset).
If your character has reached 50 or more rebirths (Reset), you cannot attack opponents below 50 reset. If an enemy who has not reached this mark has attacked you, the restrictions are removed!

If you kill another player, you are assigned the status “Player Killer (PK)”. The more players you kill, the higher your status will rise, and the character's name will start to turn red. For killing players with PK status, you get the “Hero” status and your character's name turns blue.
Clear PK status: command /pkclear, cost, 1 kill: 50 000 000 zen.
