同士討ち
In PvE zones, the player can engage in: dynamically generated missions and events that spawn at fixed locations throughout the open world, procedurally generated encounters that spawn at the player's location, on-demand missions that the player choose when and where to spawn, and world events that bring players together either to fight off the game's antagonist or to participate in group activities. The core goal of these missions is to allow the player to level up and acquire resources and equipment. Friendly fire and PvP combat is disabled by default, but a player can declare a duel with another player and engage in PvP combat.
