So I have a question about training forsaken. I have read through both the documents but am still unsure on something. To increase corruption you need to train at an intensity higher than the current corruption stat, but does the mitigating factors play a role in this. For example if I would train a forsaken with something they would normally refuse but due to the buff they now consent does that no longer affect corruption gain?
Also do you need to do another training session after exceeding the value for the corruption to take place. I ask this as I just had a situation where the value didn't increase despite being well above the current level in a stat, however if I did another training session it would have increased the stat.
Whether or not a Forsaken would refuse a training is based on a different stat than when they would gain corruption. The Obedience modifier determines whether or not they consent to training. There's a table relating the Obedience stat to its modifier in the forsaken reference.txt file. This can be a bonus, or, if Obedience is below 25, a penalty. There are other modifiers on training that are listed in the section just below the one that mentions Obedience that include having loved ones among your Forsaken, breaking vulnerabilities for the first time, and the intensity of the training.
However, whether a Forsaken will gain corruption from a training is based on a much simpler calculation. If the total training intensity is greater than their current related stat, plus 1/2 of their Deviancy, they'll gain corruption in the related stat. If they aren't consenting, they'll also gain Obedience equal to the amount of other stats they gain.
These two things, consent and stat change, don't affect each other. For example, here's Purgatory:
Hostility: 60% (Pessimistic about humanity)
Deviancy: 27% (Elaborate sexual fantasies)
Obedience: 33% (Obeys when convenient)
Disgrace: 51% (Seen as purely evil)
I have her stats basically where I want them, but we'll use her to demonstrate. If I wanted to raise her Disgrace, so that her natural cost would be less, I'd need to raise her Disgrace intensity above 51 + (33/2) = 67.5. A Grand Concert would do that, but she won't consent to Grand Concert. Her modifiers are:
+13 (obedience)
-49 (intensity exceeds current corruption)
+30 (rampant)
-6 Total
So, I'd need to raise her Obedience by about 6 points, or her Disgrace by about 6 points, if I wanted to start her off with Grand Concert.
The other way to get her above 67.5% intensity in one session would be Broadcast (70% Hostility & Disgrace). But this is even harder to do, because her Hostility is also below 70%.
Therefore, it'll take combinations of actions to get her there. The simplest action should be Attach Toys followed by Broadcast.
Attach Toys has the lowest Obedience intensity of all Obedience trainings.
Consent factors:
+13 (obedience)
+12 (accustomed to similar circumstances)
+25 Total
And now, she can no longer resist Broadcast, since she has an Obedience training applied. When I try to Broadcast now, I see this:
+13 (obedience)
-29 (intensity exceeds current corruption)
-16 Total
"You can make me go into battle, but you can't make me go along with something this big. I'll give everyone my own message, and you won't like what I have to say..."
Corruption Increase: +2% Obedience, +2% Disgrace
As you see, she goes up in Disgrace because her Disgrace intensity (70%) is now above the threshold calculated above (67.5%) The +2 Obedience happens because she is not consenting to the training, so all of her other stat changes also apply to Obedience.
An action that would cause larger changes would be Public Confinement followed by Broadcast--this would change them both by 3% instead of 2%. The reason this is different is because Public Confinement also adds to Disgrace intensity. The total intensity in a training stat is (Highest intensity + number of other trainings in that stat * 5), so it makes her Disgrace intensity 75% instead of just 70%.
Of course, all of this presumes that you have a reason to want to raise a Corruption stat. On my useful Forsaken the only one I really want to raise is Disgrace when a Forsaken costs too much. On useless Forsaken I'm trying to raise Obedience so they'll consent to the top tier trainings that allow me to drain EE from them (Drain Soul, very rarely), or deal ANGST damage to the Chosen (somewhat uncommon), or restore the motivation/stamina of other Forsaken (Grand Concert). Higher Corruption is usually not better. What do you want to raise, and why?
