The default selection of ilnesses you can contract in Fallout 4 Survival difficulty is limited at best and there are no fan favorites. Have ever had the urge to contract your beloved Ataxia or Bone Break Fever? Now you can! This mod adds 8 new ilnesses to the Commonwealth that are based on diseases from The Elder Scrolls, with effects as similar to its Skyrim (or Morrowind/Oblivion in some cases) counterparts as possible. You can get them the same way you get the original ilnesses. Keep in mind that this mod will probably not be compatible with any survival-difficulty overhaul mods that edit the HC_Manager quest.
I also felt that the issue of “Vault81 diseases” vs “Commonwealth diseases” breaks the immersion, so integrated the Molerat Disease to the list as well (diseased molerats would have easily dug a way out of the Vault by now), Vault 81 Cure (said to be supposed to heal hundreds of ilnesses) now heals any illness including the Molerat Disease which is now treated as a regular illness so you can heal it with your regular junk Antiotics. You still need something safer for children, though.
Available new ilnesses are as follows:
Ataxia: Harder lockpicking and pickpocketing
Black Heart Blight: STR -1, END -1
Bone Break Fever: Max AP -25
Brain Rot: INT -2
Rattles: Reduced AP regenerate rate (almost identical to Lethargy, has different duration but it hardly makes a difference gameplaywise)
Rockjoint: Melee damage reduced by 25%
Witbane: Gained EXP reduced by 25%
Porphyric Hemophilia: Sun damage (you take continuous damage while outside between 6AM and 6PM)
