Use this page to quickly check common questions about compatibility, licensing, and how MuMaster works in game.
General
MuMaster is a desktop macro tool for MuOnline that helps automate potion usage and combo timing. It is designed to make PvP smoother, faster, and more comfortable by reducing manual key pressing during fights.
In most cases, yes. MuMaster is built for MuOnline private servers, but the exact behavior can depend on server settings and timing rules. The safest option is to test it with the trial version first.
Pricing & Billing
Each license is valid for the selected period. Right now the main option is a 1 month license, with the possibility to renew when it expires.
Yes. A trial is the best way to check compatibility, timing, and overall behavior before buying the monthly license. It helps you make sure the app fits your setup.
Solo Player is for one PC. Guild Pack is for guilds and teams and includes up to 10 HWIDs in the same license, which makes it cheaper per PC if you need multiple machines.
Technical
HWID means Hardware ID. In simple gamer terms, it is the app's way of recognizing a specific PC. The license is tied to that machine, so if your hardware changes, the HWID can change too.
The most common causes are missing administrator rights or timing values that are too fast for your PC or server. Try running the app as administrator and increase the delays slightly for a more stable setup.
No, that depends on the server rules. Some servers allow macros, while others do not. Always check the rules of the server you play on before using MuMaster.
Setup & Support
Yes, in many cases this is required for the app to send key inputs correctly into the game. If the macro works in test mode but not in Mu, administrator rights are the first thing to check.
Yes. Side buttons are one of the key features of MuMaster. You can use them to start and stop auto potions or auto combo without reaching for the keyboard.
That is exactly why the delay settings exist. You can tune the timing to match your server limits, your ping, and your own play style for better stability.
Yes. When the license expires, you can simply renew it again for another month if you want to keep using the app.
It is designed for standard Windows desktop use. For the best results, use a modern Windows installation with up-to-date drivers and run the game and app in the same privilege level.
Yes. MuMaster is built to support both use cases. You can run auto potions, auto combo, or use the features separately depending on your setup.
