-newly acquired item using HOPE will give you 999 so consider this a cheat.
-Drop a post if there are missed items.

999 Stacks for all Items or x2 if you prefer. Use only 1 file.

You STILL need to manually stack them, auto sort does not work as it defaults to their own stacking.

Install:
1. Backup your item_data_export.Group.csv from Game Folder >  Darkest Dungeon II_Data \StreamingAssets\Excel
2. Extract (7zip or winzip) and overwrite file to Game Folder >  Darkest Dungeon II_Data \StreamingAssets\Excel

Uninstall:
restore your backup item_data_export.Group.csv
