Flyff PK System
Currently only available for those who play on the Yetti server. You must be Level 20 or higher to engage in PvP (Player vs Player) combat. You can do PKing (Player Killing) anywhere in Madrigal except towns, which are the only safe zones.
On every continent, there is a Priest of Confession whom will assist players in redeeming their PK count by summoning an angel. To be able to obtain an Angel, you must provide atleast 3 sunstones and 3 moonstones. When the Angel has appeared, you must kill several monsters and sacrifice about 50% of your current exp to the angel to prove your worth. Once you have provided enough experience points (the amount needed varies depending on the type of angel summoned), the Angel can then be turned back into the Priest and the Angel will dissappear.
White: The White Angel requires you to give it 10% of 1 level's worth of exp.
Green: The Green Angel requires you to give it 30% of 1 level's worth of exp.
Blue: The Blue Angel requires you to give it 60% of 1 level's worth of exp.
Red: The Red Angel requires you to give it 1 level's worth of exp.
