PvP Prestige
From Fallen Sword Wiki
PvP Prestige is a system where "prestige bonus" is awarded for victories over other players on attacks you initiate. Prestige is not used in the PvP Arena, in bounties or in guild conflicts)
The PvP rating gained from the victory is also credited as "PvP Prestige". This can then be used to activate the PvP Prestige skill on yourself to gain an additional xp boost for the next hour! You can view your current PvP Prestige and the bonus it would provide by activating it on the Attack Player screen.
