This was a thread where the topic of creating a playthrough for a weak character was discussed at some length. There are many good ideas, mod suggestions, configuration recipes, and other information on making a Skyrim build with existing mods, and plenty of material to inspire new mods too. Despite searching for this by the keywords in its title, LL can't seem to find it, so I've reposted the huge amount of stuff I put on there here so that I and others know where to look for it.
