Does it work well ? The company is looking for investment . <| sep |> My party and I ran something similar , in a lowmagic campaign they wanted to be ~~ difficult ~~ challenging . Massive Damage from the DM ' s Guide was turned on . Essentially rules for shock . Lingering Injuries was fun D Lots of concussions and broken ribs . Most importantly Slow healing , slightly modified . RAW it is 8 hours for a short rest , 7 days for a long rest . We changed it to 3 days for a long rest . And , of course We banned magic ! No magic initiate or ritual spellcaster feats , no subclasses bordering too close to the supernatural . No weird races either all human . GoT would work well with all of those turned on , imo . You might want to include a honor or station stat at the beginning . Something to help them move from social situation to social situation . Modify some of the backgrounds , perhaps ?
