Player vs Player

PvP covers any fight between players, from one-on-one to whole factions, nations and servers. The original Chinese release only had PvP servers, but the international servers are all PvE. That is why many newer PvP events ask you to switch on PK Mode, yet do not apply the usual PK penalty.

• Duels: one-on-one fights with no PK Mode needed. You can duel in and out of towns and in many dungeons, though some dungeons block attacks or duels. During a duel, Guardian and Spirit charms do not refill HP or MP.
• PK Mode (Player Kill): an optional status that lets you attack and kill others who are also in PK Mode, with no limit on numbers. It needs a level above 30, and once on you must stay in it for at least 10 hours. It does not work in safe zones such as towns, or in low-level areas like the Celestial Vale.
• Deathmatch Arena: matches of up to 6 against 6 that work much like the Tournament event. Entry costs silver coins. Item rewards are now worth very little, and players report that the arena is often buggy.
• PvP events: group battles such as the Arigora Colosseum, Territory Wars and Nation Wars, where factions, nations or servers fight each other. Most use PK Mode without the PK penalty.

Some Stats and Attributes do a lot against players but little against monsters:

• Spirit: strongly changes both the damage you deal and the damage you take. It is mostly found on characters who have gone through Reawakening.
• Stealth Level and Detection Level: to see a stealthed player, such as an Assassin, your Detection Level must be higher than their Stealth Level.
• Critical Damage Reduction: lowers critical hit damage from players. Monsters do not land normal critical hits.
• Charm Cooldown: makes your enemy's Guardian and Spirit charms take longer to recharge. It only matters against players, since monsters wear no charms.

No title rewards simply killing players in the open world. Titles come from PvP events, mostly the Arigora Colosseum, where your personal score unlocks them:

The first Colosseum season also handed out titles for battle wins (1, 20, 50, 100 and 200 wins) and for finishing in the top 200, 100 and 50. In Territory Wars, every member of the faction that won first place in season 9 received the title Veni Vidi Vici.
