New System: Party Quest Exploration

A new convenience system will be added that allows players to obtain equipment by running Party Quests in the background for a set period of time.

• How It Works
  • 1 Exploration Ticket will be recharged every week.
  • Players can choose their desired Party Quest and difficulty to begin an exploration.
  • Players can recruit party members to join.
  • Players can also explore solo or with a small party. (Auto-matching is not available.)
  • If the party size is small, a monster-weakening effect will be applied.
• Claiming Rewards
  • When exploration time ends, players can check and claim the equipment they've earned.
  • After exploration is complete, rewards can be claimed for 7 days. Rewards cannot be received after 7 days have passed, so please make sure to claim them before they expire.
• Reward Restrictions

  Only equipment items can be obtained through Party Quest Exploration.

  • Only equipment rewards can be obtained at set rates.
  • Other EXP and currency rewards cannot be obtained.
  • If a Party Quest Equipment Boost event is in progress, the event benefits will apply.
• Notes
  • Once an exploration begins, it cannot be cancelled. Please check the dungeon type and party composition before starting.
  • While an exploration is in progress, you cannot participate in other types of Party Quests.
  • The Exploration Ticket is consumed when exploration begins. Even if a disconnection or crash occurs during exploration, rewards will be distributed based on certain criteria.
  • If your combat power is insufficient to clear the Party Quest, the run may fail. If exploration becomes too difficult based on certain criteria, it may be terminated and your ticket returned.

3 New Legendary Artifacts Added

3 New Artifacts Will Be Added.

• New Legendary Artifacts can be obtained from existing Artifact Chests and new Rate-Up Artifact Chests.
• The Rate-Up Artifact Chest can be purchased until Wednesday, June 17, 2026, at 11:59 PM.
• Rate-Up Artifact Chests have a higher chance of obtaining new Legendary Artifacts, which means the chance of obtaining existing Legendary Artifacts is set lower. Detailed drop rates can be checked under [Rate Info] in the game.
