Hi there,

I'm not 100% sure, but I think of it this way:

You take the decimal value of the percentage and add 1.0. So, for example

Code: Select all

-8/100 + 1 = 0.92
So if 1 is your kind of baseline modifier, you have 0.92 left (only after terrain is taken into account).

Then you multiply all these numbers:

Code: Select all

0.92 * 0.85 * 0.93 * ... * 1.64 = 2.081149
which means you have an overall 208%, a modifier of +108%.

The deviation of ~1% comes from rounding being done in the shown Estimation (I think, not sure).

Best regards,
bm

Thank you for your answer but I still dont get it. I have also used chatGPT but all the values do not match with the ones in the game. Another simpler example: I have -4%, 60%, 1% and 64% modifiers and the game gives me 154%. Using your math I get 0,96 * 1,6 * 1,01 * 1,64 = 2,6434304 :?:

chatGPT gives me the following:

To find the cumulative modifier from the given percentages, you need to follow these steps:

Convert each percentage modifier into decimal form by dividing it by 100.
-4% = -0.04
60% = 0.6
1% = 0.01
64% = 0.64

Multiply the decimal modifiers together.
-0.04 * 0.6 * 0.01 * 0.64 ≈ -0.0001536

Convert the decimal product back to a percentage by multiplying it by 100.
-0.0001536 * 100 ≈ -0.01536%

The cumulative modifier from the given percentages is approximately -0.01536%. Note that the negative sign indicates a decrease or reduction.

-0.01536% looks somehow rounded up like 154% :D :?: :?: :?: :?:

I get a different result from your example, which seems to fit the +154% quiet good:

Code: Select all

0.96 * 1.6 * 1.01 * 1.64 = 2.5442304
The solution from chatGPT doesn't make much sense to me either.

A negative 10% modifier equals .9 In other words, it is 100% - 10%

A positive 10% modifier equals 1.1 That's 100% + 10%

So, using your original example: 0.92*0.85*0.93*0.96*1.60*1.60*0.71*1.64= 2.08
2.08 = 208% or put another way 100% + 108%
That's the sum-total effect of all of the other modifiers combined.
If you are attacking with a power of 1000, then a +108% modifier would change the attack power to 2080. That's the original value (1000) plus 108% of the original value (1080).

But it's more complicated than that, because combat modifiers actually apply to each individual unit and not the full attacking force. For example, the terrain modifier listed is -8%. But it's not really -8%. It might be -30% for tanks and no modifier for infantry. -8% is just the average terrain modifier for this attack.

But you really don't need to know every tiny detail to perform well in combat.

1) Keep readiness high and HQ's close to the front line
2) Know how the terrain affects your units
3) Try to avoid attacking uphill
4) Try to attack from multiple directions

As mentioned, at the total attack level the various modifiers are basically meaningless except as an indicator of how the attack is likely to go. To understand the actual effect of the modifiers on combat you have to look at the combat details. This is time consuming because the combat is resolved on the basis of individual vehicles and individual squads. The combat match-ups are random and there is a random number generated and applied to resolve the individual combat. Not only that but each individual's factors, such as Readiness, may change as the battle progresses which affects how well that individual performs in the later combat rounds.

When all is said and done the results match pretty well what would be expected from the overall match-up.
