So how do these Damage modifiers stack?

"Virulent Blessing : Target unit may add +1 to all wound rolls in the Fight phase, and wound rolls of 7+ for that unit in the Fight phase inflict double damage."
https://1d4chan.org/wiki/Warhammer_40,000/Tactics/Psychic_101(8E)#Nurgle

and

"Locus of Virulence: NURGLE All friendly Nurgle units within 6" deal 1 additional damage on a 6+ wound roll."

(and maybe the Plaguebearer Banner?)

How and in what order do these boni apply?

Q: If a unit of Plaguebearers has had the Plague Banner
Stratagem used on them, and is currently under the effects of
the Virulent Blessing psychic power, what damage do their
Plagueswords inflict on wound rolls of 7+?
A: 4.

thanks, now the other part of my question

Q: If a rule modifies a model’s Strength characteristic,
and that model is equipped with a melee weapon
that also has a modifier (e.g. ‘x2’), could you explain
the order in which the modifiers are applied to the
characteristics and the weapon’s Strength?
A: First you must determine the model’s current
Strength characteristic. To do so apply all modifiers
to it that multiply or divide the value, then apply
any that add or subtract to it. Having done this, you
then modify this value as described by the weapon’s
Strength characteristic.
For example, let’s imagine a model with a basic Strength
characteristic of 3 is under the effects of two psychic powers: a
friendly one that doubles their Strength characteristic, and an
enemy one that subtracts 1 from their Strength characteristic.
That model’s current Strength is therefore 5. If this model then
fights with a weapon like a power fist, which has a Strength
characteristic of ‘x2’, that attack will therefore be resolved at
Strength 10.

So basically you
1) Chance weapon profile to 2
2) Double damage
3) Add one

That's not actually true. That's talking about effects that alter a profile characteristic AND a weapon characteristic. For example something giving a model +1 strength (as opposed to giving the weapon +1 strength like some Khorne effects do) and also having a power fist which has a strength of x2.

Since these Nurgle rules are only affecting the characteristic of the weapon, you apply the usual "multiplication, then addition" rule. A weapon with a Damage characteristic of 1 will have its damage doubled, then have 1 added to it, for a total of 3. A weapon with a Damage characteristic of 2 will have its damage doubled, then have 1 added to it, for a total of 5.

However, Plague Banner doesn't add or multiply anything, it just changes the Damage characteristic to 2, not modify it. So a "double plus one" rule on a weapon affected by the Plague Banner would actually do 5 damage (2x2 for 4, plus 1 for 5).

Highlighted the relevant part of my previous post because BCB is blinded by all those snow flakes everywhere.

Like I said, that FAQ isn't addressing the issue here. "Damage" is strictly a weapon characteristic. Nothing on the profile is being modified.

However, the second part is correct, it just doesn't have anything to do with the FAQ you quoted.

Since snow blindness is obviously increasing, I'll explain it again for you.

My first post:

The only way to get to a 4 with "set to 2" and "double it" is by applying the "set to 2" first. Otherwise the answer would have been two.

At this point, feel free to throw all logic out of the window and go on your usual "special snowflake" rant. In that case I'll just ignore you like any other rambling mad man.

For example, let’s imagine a model with a basic Strength
characteristic of 3 is under the effects of two psychic powers: a
friendly one that doubles their Strength characteristic, and an
enemy one that subtracts 1 from their Strength characteristic.
That model’s current Strength is therefore 5

This is my second post. Since you double first and add afterwards, the order of operation for all three is fully known.

FAQ1 says "Set to X first and then double"
FAQ2 says "double comes before adding one"

Therefore, the answer is "Set to X, then double, then add one".

And yes, the rules are written badly and only solve this problem implicitly, but the answer is absolutely clear within the rules and that's all that counts when someone is asking a question on YMDC.

It seems you are the one that is snow blind. Setting to 2 is not modifying it. I am agreeing with you, but your reasoning and the FAQ are not applicable here.

We seem to have gotten some crosstalk here

So, tell me, how do you answer the question of how to resolve all three affects applying to the same unit without using both FAQ?

He already answered it.

1. Set D to 2
2. Double D characteristic
3. Add 1 to D characteristic

Order of mathematical operation remain the same as real world - GW hasn't come up with a new way of doing normal PEMDAS operation. What is not explicitly stated is that the modifications from weapon profile is considered to apply parenthesis on the former equation.

As per FAQ, if you have two S modifiers, where one MULTIPLIES it by 2 and the other SUBTRACTING 1, you follow the normal PEMDAS - 3 x 2 -1 = 6 - 1 = 5
If you have a powerfist that modifies strength by x2, which is a modification from weapon profile, you then get the resulting equation: (3 x 2 - 1) x 2 = (6 - 1) x 2 = 5 x 2 = 10

How do you know whether to double or set 2 first?

It'll depend on what your definition of "change D characteristic from X to Y" is.
Note "change" is distinct from "add" or "multiply".

And that definition is given by the first FAQ.

So you need both FAQs to answer OP's questions.

To which you and BCB for reasons unknown to me disagree.

Can we now stop this stupid exercise?

so the plaguebearers do 3 dmg when they got the blessing and are in range of an hq? and 5 when the banner is activated?

Assuming you roll high enough on your to wound roll, yes.

Fully buffed a roll of 5 will yield 3 damage, a roll of 6 will do 5 damage and all other successful rolls will do 2 damage.
