  • Displaying critical information such as gutterlines, dead cells, skill range, monster detection box, and frames per second
  • Enabling the use of custom Homunculus AI on newer clients
  • Fully customizable using an easy-to-use config file
  • In game commands for toggling features
  • Comes built in with the basic NovaRO installation; no need for additional downloads


NovaExt is active by default, and players can start using NovaExt commands as soon as they've logged into their character.

The user friendly interface is located bottom right of your NovaRO Patcher labelled NovaEXT Settings (Yellow Toolbox Icon)

NovaExt can be customised by editing the NovaExt.ini file inside your NovaRO folder.

Full notes on customisation can be found Here

Enabling Turbo/Smart Casting

  • Make sure you have /battlemode enabled and set up in-game.
  • Go to your NovaRO folder and open NovaExt.ini file using Notepad or a similar program.
  • Scroll down and find the “Keyboard settings for turbo mode.” Here you can change the behavior of the keyboard button that corresponds to your hotkeys.
    • 0 = Turbo disabled. Manually press the keyboard button and click to cast skills normally.
    • 1 = Turbo enabled by holding down the keyboard button. You still have to manually click the target to cast skills.
    • 2 = Turbo enabled by holding down the keyboard button and hovering the cursor on top of the target. You will continuously cast the skill on the target as long as you hold down the keyboard button and your cursor stays on target.
  • For example, if you would like to enable Turbo mode 2 on your keyboard's Q button, go to the corresponding keyboard setting and change it into 51=2.
  • Save the changes you made after you're done setting up.
  • In-game, use the Pause button on your keyboard to toggle Turbo mode on and off.
    • If you exit the game leaving Turbo enabled and are unable to login, you can use the Pause button here to toggle it off and type normally again.
  • Alternatively, you can use the /turbo text command to toggle Turbo. You can bind this command into an Alt + M shortcut.
