In addition to having to contend with the violent denizens of Rubi-Ka, it is sometimes necessary to engage in combat with other players.

PvP can only be done in districts with lowered suppression gas. At 25\% suppression gas, opposing factions can fight eachother. At 5\% suppression gas, any players who do not belong to the same organization may fight eachother. At 0\% suppression gas, anyone can fight anyone.

It is also possible to engage in a duel with another player. Simply target and type /duel to initiate the duel request. To automatically ignore duel requests, [F10] -> Behaviour -> Behaviour Settings -> PVP

In addition to suppression gas and the /duel command, a player can only fight another player if the level difference allows for it.
