What to Contact Us About
You can contact MUOnlineTools to report incorrect values, suggest improvements, submit formula testing, share updated market information, request collaboration or ask about advertising opportunities.
For formula submissions, the most useful information includes your character class, relevant stats, equipment changes, buffs used, before-and-after values and screenshots where available. The more controlled the test is, the easier it is to verify.
Corrections and Updates
MU Online values can change between seasons, patches and regional updates. If you notice that a calculator, table, price estimate or forecast no longer matches Global MU Online, please send the details so it can be reviewed.
Market prices, fifth wing values and event timing are especially likely to change over time, so community feedback helps keep the site more accurate for everyone.
Can I submit formula data?
Yes. Controlled before-and-after tests are welcome, especially when they isolate one stat, item option or buff at a time.
Can I suggest a new calculator?
Yes. Suggestions are welcome if they would help Global MU Online players make better decisions or understand a system more clearly.
Can I advertise or collaborate?
Yes. Please email the details or review the Advertise and Collaborate pages for more context.
