PvP

From Flyff Wiki

PvP stands for Player versus Player, and is a term used to refer to any activity in which players fight each other. Despite the fact that Flyff is generally not considered to be a well-balanced game, PvP remains moderately popular.

The following are Player versus Player activities:

• One-on-one duels
• Guild Siege
• Combat in the PvP arena
• PKing (only available on the Demian Server)
