I've been working on these house rules for quite a while. They come after about a year of playing the game. They're for Lamentations of the Flame Princess as the title indicates. Overall while they change some sections of the game drastically, I try to stay true to what I consider to be the spirit of LOTFP and simply refine existing ideas or fill in gaps with new ideas.

You can comment on the google doc. Please comment if you find any mistakes or imbalances or other issues. These rules very much are a work in progress.
