Introduction
PvP mode is an optional mode for players who want to experience the dark World of Darkness at its fullest. While in PvP mode, you don't need a firm reason to attack another player as long as the target is also in PvP mode. The classic (SA-MP) "roleplay" reasoning for attacking is still needed if a PvP player is attacking players who are not in PvP mode. PvP mode doesn't apply for scripted combat. Regardless, senseless killings won't be tolerated.
PvP Reasoning
There is no invalid attack reason as long as you roleplay by your character's concept. Hybrids, for example, can kill anyone and anyone can kill them just for the mere fact they are Hybrids. Same logic can be applied to Hunters. Vampires and Werewolves conflict can be reasoned with the same logic, BSD and Silver Fangs, Technocrats and Traditionalists, Sabbat and Camarilla, etc. Note that you need still to find out IC-ly about a certain character's race or affiliation.
Parties
When it comes to PvP parties, anyone can be killed by anyone without being accused for DM as long as the scene is not completely senseless. A PvP party is considered a group of characters where the majority are PvP players.
Deaths
Dying in PvP mode grants one free death, meaning you will not suffer XP or attribute loss on the first PvP death.
This triggers a 48-payday cooldown.
Updated rule:
If the character dies again before the cooldown expires, the character is permanently killed (CK).
This replaces the old “second death = XP/attribute loss” system.
Bonus Experience
PvP players get extra experience points spawned. The first experience point gets spawned when a PvP player collects 24 paydays, the second experience point will be awarded after another 23 paydays collected and so on. The rate at which PvP experience will be given will improve until it drops down to 1 experience point every 6 padays. If you've spent more than 50% of the payday in AFK mode (/(h)ouse sleep); that payday won't count for PvP extra experience. Once you die the PvP experience rate gets reset to 1 experience point every 24 padays collected and you need to start over as if you just switched to PvP.
Commands
The command to toggle PvP mode is /(tog)gle(pvp) and it is also good to know that it takes 3 paydays to disable PvP mode and another 3 to enable it. Informaton about PvP mode and "free death" cooldown can be checked via /e(xp)erience(log) command. /id command prints out whether a player has PvP enabled or not while /pvplist lists all PvP players online. PvP players get a notification every time a non PvP player enables PvP mode.
