I made the original version of this tool for the F&S server, so I and others could get the most out of gold spent on merging - but seeing as merging is on Path to Pandora too, I've updated it quite a bit just today.
There's three functions:
- Merge cost in both res and gold
- Number of troops you can merge per gold
- The closest optimal merges for a desired amount of troops
For more details, check the functionality tab in the tool.
Let me know if you encounter any issues or have any suggestions, cheers!
