Server maintenance scheduled for December 11th, 2023 at 06:00 UTC

Server maintenance will occur on December 11th, 2023 at 06:00 UTC.

We anticipate the maintenance to take anywhere between 30 to 60 minutes to complete.

Also, just FYI, this maintenance is not to start the Christmas event. :’)

Thank you for understanding!

Server maintenance has completed for December 1st, 2023. (サーバメンテナンス完了 12/2)

Update: Maintenance has been completed! (Sorry to keep you waiting. > Everybody)

Apologies for the short notice, but we will be doing a short maintenance in about an hour from now.

I need to apply a patch to the ship servers and want to get it out of the way before everyone settles in for the weekend.

I realize there was maintenance earlier this week and, after this one, don't expect any further maintenance.

Thank you for understanding and I apologize again for the inconvenience.

UPDATE: Maintenance has been completed.

Server maintenance will occur at 20:00 UTC on November 29th, 2023.

I will be making some back-end changes to the game servers and the game will be unavailable for anywhere from 60 minutes to 90 minutes. (If it ends up being longer than expected, I'll update this post.)

Thank you for understanding!

Server maintenance completed for November 25th, 2023 (サーバメンテナンス完了 11/26)

Server maintenance has completed.

Ephinea.dll was updated to v1.504 to fix a rare issue with the DMC patch and the Dragon bosses. Due to latency, the boss could die early on a client's screen and other players tagging the boss could cause negative damage values to be sent from that client to other players. This could sometimes heal the boss before the boss died on the party leader's screen. This should now be fixed. Let us know if you run into any problems with the DMC patch and provide as many details as possible.

The Forge was updated to fix the Hunter Guild's NPC dialogue, allowing players to return to the lobby without using the /lobby chat command.

Fixed the description for the Standstill Shield skin of Red Ring in the English unitxt.

Server maintenance complete for November 18th, 2023 (サーバメンテナンス完了 11/19)

Maintenance has finally completed after much testing of some changes.

A new, much better fix for damage cancel was implemented in the server and client. This fix makes significant changes to how PSOBB sends, receives, and processes damage and kill packets. This fix has been tested considerably and we believe it is ready and should be always on. The old damage cancel mitigations in the server have been disabled because they are now obsolete thanks to this new patch. If you find any issues, please let us know and provide as many details as possible.

The following changes have been made to Anguish.
  • Freeze traps and Frozen Shooter/Snow Queen work again.
  • Arrest, Confusion and Freeze lengths are 60 frames across all Anguish difficulties.
    • For comparison, these last 210, 300, and 150 frames respectively in Ultimate difficulty.
  • Demon's activation rate is 15% base. (Comparison to Ultimate mode where it is 50%.)

When a trade window is active, ES weapons with specials will show the special after the weapon type. For example, "ENDER Needle [Hell]". Note that there is a limitation here--some ES weapon specials are not in the unitxt. The "HP Regeneration" and "TP Regeneration" specials are currently coded into the client but will be added to the unitxt at a later date.

When inspecting a weapon's attributes in a trade window, attributes that occupy slot in the item data but are 0ed, such as 5% Native that was down tekked to 0% Native, will now show a red 0.

For characters with /showwep enabled, nonrare weapons will show the special that they dropped with instead of "???? Handgun" for example. The weapons can still be tekked up and down as normal.

Fixed a rare bug where PSOBB would fail to decrypt the encrypted password from the registry. This meant specific username and password combinations could not login using the saved information and users would need to re-enter their credentials at the main menu, or change their password for saving to the registry to work properly.

Line primitives, such as Forest 2/Gal Gryphon rain and the Epsilon/Canadine lasers, will now scale by default based on your resolution. These were previously drawn as a single line with a width of 1 pixel, which made them very difficult to see at higher resolution and near impossible if you used SSAA.

Zu, Pazuzu, Dorphon, and Dorphon Eclair monsters will always drop their items at their spawn point and not where they died. This is intended to solve issues where these enemies often go out of bounds or to parts of rooms that are blocked off in EP4. This is experimental--let us know what you think about it.

Fixed an issue where a boss wouldn't drop an item if the party leader was dead or did not tag the boss.

Fixed an issue in the client where boxes would not drop items if the boxes had not yet spawned for the party leader. This was often seen at the Episode 4 Boss when the leader was stuck in the "You are the hero" screen a bit longer due to desync.

Fixed a rare issue where experience may not be distributed to any player when experience share was enabled. This would occur if no players claimed full experience for a monster.

Fixed a rare issue where partial experience may be distributed to clients in experience share because only the first full experience request was honored. If multiple clients believed they got the last hit on a monster, only the first one received by the server would be honored.

Fixed the rare enemy rate for Battle and Challenge Mode--this was incorrectly set to 0% so these modes have not spawned any rare enemies in a few years. They will now spawn following the base rare enemy rate of 1/500.

The launcher was also updated. There are scaling options for the rain and laser line primitives mentioned above. Also, the "Custom" resolution option was removed since the launcher has already queried DirectX for supported resolutions for a while. Custom resolutions only work when you create them in your GPU's control panel anyway. When you do it this way, they show up in the launcher as well since they will be presented to DirectX.

NOTE: The launcher's internal web browser will use the WebView2 class (which operates on Chromium), if on Windows 10 or higher. Otherwise, the launcher will use the old WebBrowser class which operates on Internet Explorer and all risks associated with it.

The launcher's internal web browser has moved from the old WebBrowser class, which operated using Internet Explorer, to WebView2, which operates using Chromium. This makes the launcher no longer compatible with Windows 7 or 8/8.1. You need to be running Windows 10 or higher to use the launcher.

This was done for security reasons. Internet Explorer has been retired and no longer receives security updates. Windows 7 and 8/8.1 are also not compatible with the latest version of WebView2 and we refuse to use an older version of WebView2 which would be compatible, but not updated with security patches and fixes. The previous launcher can still be launched, if needed, through online_win7.exe, but will not be receiving any updates going forward.

The Red Ring Plating items are now available in a new shop quest called "The Forge." In this quest, you can acquire a free Neutralizer or Red Paint, and you can trade certain items for the Red Ring Plating items. The trade lists are intended to provide some value to certain items that hold little to no value, such as monster parts, as well as a few rare items for some of the more desired plating items. You can find this quest under Episode 1 → Shop.

I think that's everything. Let me know if there are any issues and thank you for playing on Ephinea!

  • フリーズトラップとフローズンシューター・スノークイーンが元通り機能するようになりました。
  • 麻痺・混乱・凍結はすべてのAnguish難易度で60フレームになりました。
    • 比較までに、アルティメットではそれぞれ210・310・150フレームとなっています。
  • デーモンの発動率は15%になりました。(アルティメットでは50%)
トレードウインドウがアクティブな場合、スペシャルアタックを持つES武器は武器タイプの後ろにスペシャルが表示されるようになりました。例えば、"ENDER Needle [ヘル]"のような表示です。なお注意点として、いくつかのES武器のスペシャルは現在unitxtに未実装で、HPリジェネレーションとTPリジェネレーションは現在クライアントにコードされていますが、後日unitxtにも実装される予定です。







クライアントサイドで、パーティリーダーがのボックスがまだ出現していない状態で箱を破壊した場合にアイテムがドロップしない問題を修正しました。これはEP4のボスでリーダーが同期の問題で"You are the hero"画面で少し長く待機しているときによく見られた問題です。



ランチャーの内部ブラウザがInternet Explorerを使用する古いWebBrowserクラスからChromiumを使用するWebView2に移行しました。これにより、ランチャーはWindows7または8/8.1と互換性がなくなりました。ランチャーを使用するにはWindows10以上で実行される必要があります。

これはセキュリティ上の理由からです。Internet Explorerは更新が停止され、セキュリティアップデートがされていません。また、Windows 7と8/8.1はWebView2の最新バージョンと互換性がなく、互換性はあってもセキュリティパッチや修正プログラムが更新されていない古いバージョンのWebView2を使用することを拒否しています。旧バージョンのランチャーは、必要に応じてonline_win7.exeから起動することができますが、今後アップデートを受けることはありません。

新しいショップクエスト "鍛冶屋"でレッドリングのメッキアイテムが入手可能になりました。このクエストでは、「中和剤」や「赤いペンキ」を無料で入手できるほか、特定のアイテムとレッドリングのメッキアイテムを交換することができます。トレードリストは、モンスターのパーツなど、ほとんど価値のないアイテムに価値を与えるためのもので、レアアイテムとメッキアイテムを交換することができます。このクエストは、エピソード1→ショップから受注できます。
