So I wanted to make skill choices a lot more relevant for every hero, by bringing a lot of skills closer in balance, and doing the same for paths as well, though those are more specialized.  This now covers most of the classes and changes I wanted to make, I'm still open to ideas, but just wanted to thank everyone who has give feedback and suggestions so far.

This mod has every change split off into its own file to make it future proof to updates, it also won't overwrite any of your files, and is easy to remove. There is now a separate zip for text/tooltip fixes since some are hardcoded into the game, so changes I make won't be reflected, and if I add new modifiers they sometimes won't display on the tooltip properly without the text file.  It's not required for functionality though, just readability.

Installation:

Open the Balance Overhaul zip file, and extract all the files into
...Steam\steamapps\common\Darkest Dungeon®  II\Darkest Dungeon II_Data\StreamingAssets\Excel
Open the Balance Overhaul text zip, extract the files into
...\Steam\steamapps\common\Darkest Dungeon® II\Darkest Dungeon II_Data\StreamingAssets\Localization\Sources
To uninstall, extract the files into the folder again, choose to replace, they should all be selected, hit delete.


All changes are in addition to the base abilities unless stated otherwise.
