Disclaimer
Use at your own discretion. Running userscripts always carries some risk, including the possibility of account restrictions or bans depending on site policies. This script is safe from a malware perspective, but you should still be cautious when installing any third-party extensions or apps outside your main browser. The script was designed with PCs in mind, and while it may work on mobile, behavior can vary — for example, auto-scrolling, HUD placement, or background tab handling might not function as expected.
Description
This userscript automatically farms stamina for the game Veyra on demonicscans.org by clicking on reaction buttons across manga/manhwa chapters.
Once enabled, open any chapter from any series (ideally a long-running one like One Piece) and the script will:
- Scroll to the reaction button and click it.
- Automatically move to the next chapter and repeat the process.
- Show a small on-screen HUD with your current stamina and farm progress.
- Pause if you are within 30 stamina of your maximum.
- Stop completely when the daily farm limit (e.g.
1000/1000) is reached. - Allow manual pause/resume with a toggle button in the HUD.
How to Use
- Install Tampermonkey (or another userscript manager) in your browser.
- Install this script from GreasyFork.
- Go to demonicscans.org and open any manga/manhwa chapter.
- The script will begin farming automatically:
- ⚡ Clicks reactions to gain stamina.
- ➡ Moves on to the next chapter.
- 🌾 Stops when you reach the daily farm cap.
- Use the Pause/Resume button in the HUD at any time if you want manual control.
Known Issues
- Some ads may stop the website from loading properly. The script was tested after using uBlock Origin and works correctly with it enabled.
- Mobile devices may behave differently due to auto-scrolling, HUD placement, or background tab handling.
