Players Below Protection Level 150

• Changed the PvP protection system for players below level 150.
  • Players level 150+ can attack players below level 150 without receiving a Skull, gaining Frags, or receiving PZ Lock.
  • PvP Mode must be enabled, but there is no need to disable Safe PvP or change the attack level.
  • Players below level 150 cannot attack other players.
  • They can still die normally to monsters, including inside town range.
  • If another player would kill them, they will instead be teleported back to their temple.
  • This protection applies only within the entire town area and does not apply outside town.
• This change was introduced to prevent low-level characters from being used to interfere with or abuse the PvP system.

Target Visibility

• Changed the visibility requirement for targeting players with spells and weapons.
  • Players can now only attack or heal another player if both characters can see each other.
  • Seeing only the player's name at the edge of the screen is no longer sufficient.
  • This mainly affects situations around the northern and southern edges of the screen where a player's name could previously be visible while their character was not.
• No spell, weapon, or attack range has been changed or reduced.
• The change only affects the visibility requirement of the target.

Inspect Visibility

• Added a new Player Settings option to Allow Inspect:
  • All — Everyone can inspect you.
  • Guild — Only guild members can inspect you.
  • Party — Only party members can inspect you.
  • OFF — No one can inspect you.
• You still can inspect yourself to check your stats always.

Damage Number Display

• Added a new Player Settings option to change how damage numbers are displayed:
  • Normal, k, m, b
  • The option is disabled by default.
  • The selected format is also applied to the Server Log.

Behemoth Spawn

• Added Vampires to the Behemoth hunting spawn.

Boss Loot Messages

• Added rarity-based colors to Boss Loot messages.

Map & Spawn Updates

Hourly Bosses

• Modified the spawn locations of all hourly bosses.
  • Bosses now spawn on a separate floor or behind walls with a door.
  • This prevents Cave Bot users in nearby hunting areas from accidentally entering boss areas and triggering an AFK Check.
  • Players using Cave Bot should update their waypoints to avoid entering these areas.
• While an hourly boss is alive, you can check its exact spawn location using:
  • !exiva BOSSNAME

Map Fixes

• Fixed several reported map issues.
• Fixed an issue that allowed players to Browse Field on house tiles.

Client Updater

• • Improved the updater to automatically retry failed or interrupted downloads.
  • If an update fails or the connection is lost, the updater will retry automatically:
    • 5 seconds, 10 seconds, 15 seconds and so on up to 60 seconds.
  • Once it reaches 60 seconds, it will continue retrying every 60 seconds until the update succeeds or is cancelled.
  • This prevents failed updates from requiring players to restart the client and begin the update process again.

  • If an update is available after a server save or relog, the client will automatically download and apply it.

• Make sure to apply the required updates before attempting to log in after the server save.
• The latest client version will be required to log in after the applicable server save.

Windows Defender

• Some Windows Defender installations may incorrectly detect the updated client executable files as malware.
• This is a false positive caused by the executable files.
• Keeping Windows Defender and Windows fully updated can help prevent these false detections.
• Updated client files will also be available on the website Download page with the next server save.
• If you prefer to download a fresh client, remove data.zip from:
  • %appdata%/OxygenOT/OxygenOT IX_v4
• Then start the client normally.

Notes

• Some changes are live and rest will be live with next server save.
• Make sure your client is updated to the required version before the next server save.
