Player Versus Player, or PVP, is a combat mode that allows players to fight and kill other players, as opposed to PVE. Many different MMORPGs offer PVP in some way or form within their games. Features that support PVP will be available in Tree of Savior. There won't be random field PVP, but the developers are planning on tournaments that can be entered alone or in parties. A PVP leaderboard is already implemented in each player character's Adventure Journal.
