Luck in Survival mode affects illness?

[ut]

This is the first time I tried survival mode. So I built a character who started with 1 luck and 1 agility. At first I used normal difficulty to rescue Preston, everything seems fine until I switch to survival difficulty...
It seems my character can't stay health for 1 day without getting sick and has a high chance to get infected after a combat. Since my level is low it is hard to find a doctor, I have to travel all the way to Diamond City or Covenant. This is really annoying.

I don't think luck plays that role in survival. I could be wrong tho. I believe it has to do more with criticals and things you find in containers etc. Somebody probably could elaborate further.

A lot of good info here:

My memory is a little fuzzy on the details as I just started playing again, but from what I remember both endurance and luck affects the chance of contracting an illness. At least that's the impression I have gotten after running multiple builds through survival mode.

SPECIAL doesn't affect illness in Survival at all. It's only based in actions that increase disease risk and/or trigger the game to perform a roll dice to check if disease should be applied, which are:

-Using consumables: food, drinks, chems. Chems and big ration foods have increased disease risk.
-Cannibal perk eating
-Dunking youself in water: swimming, walking underwater(power armor wise) and rain.
-Getting hit in combat: all hits have minimal chance. Some others like molerats, ghouls have increased chance and trigger a check for disease.

Very generally you get a disease risk pool that increases when any action with a disease risk attached. If the action triggers a disease check too then a dice is rolled against the disease pool, but the disease pool won't be cleared. Think on a dice roll challenge in tabletop RPG against a number which represents difficulty or likelihood, same system here.

Every time a certain value in the disease pool is reached a roll dice is forced and the disease pool value is cleared(chance gets reduced to minimum). Sleeping does this too, so every time you sleep in a bed a dice roll is made and the disease risk pool clears.

Edit: Cool. Steam might be borked because when I replied it showed no replies but now I see all of them. Thanks, Valve.

Not as far as I know. The only disease Luck affects is the Vault 81 molerat disease. It can reduce your chances of getting it if you are bit but I think it needs to be pretty high.

Also, pretty much everything you do increases your chance of getting a disease at the next disease check. Eating food, using addictive chems, drinking Nuka-Colas, being hit by disease carrying enemies (ghouls, animals etc.), swimming in 'dirty' water (read: irradiated, which is pretty much all of it), drinking dirty water, being in the rain and sleeping in beds/mattresses/sleeping bags that are outside. I might have missed some other factors, like maybe alcohol and I'm not sure if Stimpaks count towards chem use.

Rad-Away and Mysterious Serum increase your chance for catching disease by 25%; 20% from the temporary Immunity Suppression de-buff and a separate, permanent 5%.

Each of those adds a certain percentage to your risk of catching a disease. When you get to 25% risk, the game starts rolling every time you perform an action that adds a chance to your disease risk (except drinking Nuka-Colas iirc). Then you have to take into account the RNG of the rolls when they happen; from between 5-90% chance per roll. Once you get a disease, not only does it reset the risk pool for getting a disease but also makes you immune for 24 hours.

Thanks for your replies guys.

I think I'm getting used to it, sort of. As long as the illness doesn't kill me, I can ignore it until I feel it is necessary to take antibiotics.

By the way it seems the game has a bug that even if you are inside a house, you still look wet if it's raining. Also radioactive storm ignores doors?

The only diseases that are really a life or death issue is Infection (Periodic Damage) and Weakness (20% increased damage taken). They also go away after a week of in-game time.

Going into a building isn't enough to stop a rad storm affecting you, unless it leads to an interior cell.

Parasites has a lot of implications despite not affecting HP. You have to eat double amount of food, which hits your stock to the point that even using antibiotics is cheaper than paying the extra food...not counting just visiting to a doctor and ask for a heal(15 caps). Also more food means potentially more rads, so you have to counter increased radiation too.

Going around with parasites is a great way to ultimately end up dying due to resource constraints or other associated debuffs.
