Attacking players and self-defense





Outside a duel you can attack other players (hold Ctrl while clicking), but the game discourages it. When someone hits you, a self-defense window opens and you may kill the attacker for a limited time without penalty. Hitting an Elf's summoned creature also triggers self-defense. Killing a player who had no self-defense against you makes you an Outlaw, usually called a PK (player killer).
Outlaw levels and PK points
Since Season 9Season 9 moved PK status to a point system. Points start counting from PK level 1, keep piling up past level 3 with no cap, and go down only as you hunt monsters: each kill removes points equal to the monster's level divided by 2. Pasi the Mage in Lorencia shows your current points.
| Level | Points | Name color | Item drop on death |
|---|---|---|---|
| Normal | — | Yellow | 6% by monster, 0 by player |
| PK 1 (Warning) | 21,600 | Orange | 25% |
| PK 2 | 43,200 | Red | 50% |
| PK 3 (Murderer) | 86,400 | Crimson | 90% |
| Beyond PK 3 | +3,600 per step | Crimson | 90% |
Other Outlaw penalties
Since Season 9| Level | XP lost on death by a monster | Warp Command Window |
|---|---|---|
| Normal | 3% (level 11–150), 2% (151–220), 1% (221+) | Normal Zen cost |
| PK 1 (Warning) | 5% | Normal Zen cost |
| PK 2 | 10% | Shown Zen ×50 |
| PK 3 (Murderer) | 20% | Shown Zen ×50 |
- Dying to a monster costs 4% of your Zen, taken from both inventory and warehouse, at any PK level. Dying to a player costs no Zen, and characters at level 10 or below lose none.
- From PK level 2, reconnecting always puts you in Lorencia.
- At PK level 3, points only drop by hunting monsters in Vulcanus.
- From PK level 1 you cannot join Non-PvP servers, and Blue Gold channels are closed to you as well.
Hero status (older rules)
The fan wiki describes an older Hero status. You became a Hero by killing three or more 2nd-stage Outlaws in one login session without letting them hit you; a kill made under self-defense did not count. Heroes had a 1 in 32 chance to drop an item on death and lost less experience to monsters. The status lasted one hour and the timer reset with each PK you killed.
Duels, guild wars and Battle Soccer
If you want to fight without becoming an Outlaw, use the built-in systems. The Duel System lets two non-PK players fight without being flagged for the kill. Guilds can challenge each other to a guild war, or to Battle Soccer in the Arena at any time. Bigger fights happen in Castle Siege and between the two Gens; see Guilds & Alliances for guild basics.
| Command | What it does |
|---|---|
| /duel | Challenge the player you point at to a duel |
| /war | Declare a guild war on the named guild |
| /battlesoccer | Challenge the named guild to Battle Soccer |
| /request | Turn incoming trade, party and other requests on or off |
PvP areas
Since Season 9Season 9 also changed where PvP is allowed. Atlans and Aida became normal areas, and the guide lists which zones allow PvP on Red and Blue servers.
| Area | Level (warp) | PvP on |
|---|---|---|
| Atlans | 60 (70) | Blue only |
| Aida | 130 (150) | Blue only |
| Kanturu Ruins | 160 | Blue only |
| Swamp of Peace | 400 | Blue only |
| Vulcanus | 30 | Red and Blue |
