how do forts work

[Ctanr]

Hey guys, something is ununderstandable for me...

according to the wiki every Level of a fort reduces the attack and defense of the attacking units by 15% but if the attack and defense is calculated as: 1-(n*0,15) where n is the level of forts the attack and defense of a unit attacking a level 10 fort would actually be negative....

my gues would be that it is like 0.85^n which would mean that a unit attacking a level 10 fort would have about 20% of its normal attack and defense

what do you think?

i think their procent calc works more like 10-100% = 5

For a moment there I thought I was in the EU4 forums and wanted to write: nobody knows...

i dont know if the swedish school teaches a different kind of percentage math than the german ones, but according to what ive learned in school that wouldnt make any sense

I think its to factor in engineer bonuses and battle damage (you have to attack/bomb for a while to destroy their forts)

You're right, but we have to remember that the percentages may be applied in a weird order here. Paradox tends to use all percentage values as pp because it's simpler to understand, so if you get two 50% bonuses, that adds up to a 100% bonus (not 125%). This means penalties greater than 100% won't necessarily put the unit into negatives either, just undo a corresponding amount of positive bonuses.

maybe it is 15% applied in row not summed up, would als omake the first levels more effective.

math: 100*0.85*0.85*0.85*0.85*0.85*0.85*0.85*0.85*0.85*0.85 or 100*0,85^10 = which would be 19,7% attack and defense stat remaining.
I think this actually m akes sense.

thats the second part of my op

my gues would be that it is like 0.85^n which would mean that a unit attacking a level 10 fort would have about 20% of its normal attack and defense

Also, Wiki might be just plain wrong.

I thought you can only build forts up to level 5? But, I could be wrong...

the wiki says that the max level is 10

Do forts work better if I station divisions with Engineers in them? Or are Engineers just for attacking forts?

Mentioned explicitly in WWW that engineers are mostly for defense.

It could be fragmented percentage, so :

Lvl 1 fort would provide 85%
Lvl 2 would provide 15% def from 85%, so 72,25% and not 70% etc... So your nerver reach 0.

 

[Concept2D]

Based on how the other modifiers are calculated and how it worked in HOI3, it's probably additive

So lvl 2 fort gives -30%
lvl 5 gives -75%
lvl 10? gives -150%

If I attack at 130% normally a lvl 5 fort will turn it into a (130-75) 55% attack.
If it's a level 10 fort I attack at (130-150) -20%, which will be changed to either 0% attack, or whatever the guaranteed minimum attack is

Note there will be plenty of modifiers to cancel out the -75% or -150% (if they go to 10) such as
- Engineers
- General Skill level
- General Specialist skill (e.g. Fortress bunker)
- Very experienced Troops
- Planning bonus
- Air superiority
- Attacking from multiple directions
- .......

So attacking the maginot line will be expensive but not impossible for the Germans, as it should be
