This mod simply delevels all of the leveled items and leveled npcs down 1.Which means everything will be harder (npcs) and high level loot will be easier to get.
Its a bit of a trade off. these high level npcs that spawn at level 1 are gonna be hard to deal with.
Its a bit unbalanced of course. I would recommand a total of 30 followers.
Also i would keep the difficulty at normal, unless you like gimping yourself even more.
