Here's a 'not that useful' Aion tool. So what does it do;
- Repacking files in .pak (aion data file format)
- Finding client_items.xml in it
- Modifying it in memory depending on input files (a few examples come with archive)
- Saving modified file
A hint: If you run it in aion item folder it'll directly patch new file for trading dark poeta items (will not work on server sided checking) without needing console parameters.
