This is now Dwarfmaster1974’s 2nd mod, which he is happy to share with you.
This mod doesn’t actually do that much, and has just little effects on the game itself. It only shows a current rank in the list of buffs.
This rank can be reached by reaching a certain player level. This must/can be configured in the buffs.xml.
Also, have a look at the README.md for instructions and help.
Works both locally and server-side.
The forum topic of the mod is here.
