07.10: Update

2026-10-07 20:13:40

Today's update is live. The BETA client has been updated to 2.1.17.

PK penalties

  • Each uncleared PK kill reduces physical and magic attack power and defense by 10 percentage points, up to a maximum penalty of 90%. Existing uncleared PK kills also count.
  • The penalty decreases as you clear PK by killing monsters. Clearing one PK kill now requires approximately six times as many monster kills.
  • Allocated character stat points are preserved. The penalty is applied in combat calculations.
  • PK clear on the website now costs more: every next kill costs 50kk zen more than the previous one (1st kill 50kk, 2nd 100kk, 3rd 150kk…). For example, 3 kills cost 50kk + 100kk + 150kk = 300kk.
  • Each character can use PK clear on the website only once every 24 hours.

Talismans

  • Talisman of Mobility now supports Kalima, including Hidden Kalima.
  • Talisman of Resurrection now supports Kalima and Castle Siege, Crywolf, Barracks and Refuge maps.
  • Returning to Land of Trials requires access: the area must be open to everyone, or your guild or alliance must have permission. Access is checked before teleporting.
  • Saved-location tooltips now show the correct map name even after moving to another map.

BETA client

The character window C now shows your current PK attack/defense penalty. A PK status icon also provides a hover explanation. Both disappear once the penalty is cleared.

Start Launcher and let it update the client before entering the game. A full client download is not required.

Welcome to the Autumn Season – Golden Colossus!

2026-10-01 00:39:43

The Autumn Season is here, bringing new rewards, client improvements, and a new Castle Siege participation streak system!

Golden Colossus

Golden Monsters now have an additional combined chance to drop a class-themed box from the Fruits for Box quest:

  • Golden Goblin — 10%
  • Golden Titan — 15%
  • Golden Tantalose — 25%
  • Golden Erohim — 45% (10% Zen chance — 500kk)
  • Golden Hell Maine — 70% (10% Zen chance — 750kk)
  • Golden Kundun — 100% (10% Zen chance — 1kkk)

New Client

We are still actively working on the new client, which is now available from the main page.

Why is moving to the new client important?

The new client gives us almost endless possibilities for future development:

  • Much better FPS and overall performance
  • More freedom to improve and customize the game
  • Ability to create completely new events
  • Custom features and mechanics that other servers may not have
  • Much greater potential for future updates

Thank you to everyone who has been reporting bugs and helping us test the new client!

If you haven't tried it yet, now is a great time to give it a try.

The old client will not be shut down yet. We will continue supporting it until new features or events are ready and there is a clear reason to move completely to the new version.

Castle Siege Participation Streak

Starting with the next Castle Siege, we are introducing a new Castle Siege participation streak.

Your participation will be tracked continuously and will carry over between seasons and epochs.

Players will receive additional Grand Reset quest completion bonuses based on their Castle Siege streak:

  • 1st CS → 100 quests
  • 2nd CS → 100 quests
  • 3rd CS → 200 quests
  • 4th CS → 100 quests
  • 5th CS → 200 quests
  • 6th CS → 100 quests
  • 7th+ CS → 200 quests
  • 10th+ CS → 300 quests

The bonus increases as your participation streak progresses, with additional milestones at 3, 5, 7+, and 10+ Castle Siege participations.

 

Good luck this season, and thank you for continuing to support the server!
