Lords and Ladys of Stormfall

continuing with some post about calculating battles here i give you one about how wto know how much defense still remains in a target after missing the first hit

First of all, you need to know - as precisely as possible - how much offensive points was sent in the attack (ideally, before you sent the attack, by checking the points sent in the lower left of the attack screen).  If you cannot have the number from the beginning, use a typical spreadsheet to evaluate what was sent. And always consider the Lost Arts to be at level 20 (40%). 

1.-Calculate my loss percentage in the battle.

Fist, im going to give one example attack using some kind of troops with an offensive power total of 300.000 points

You calculate the Battle Loss percentage (%) by dividing the troops killed by the total troops of the largest unit group sent. In my example, the largest unit group i have sent is 1,000 Paladins and 900 died. you have to divide 900 by 1000 and that gives you 90%. 

So, that means that the Battle Loss % is 90%. Meaning that my entire attack was 10% of the battle. 

2.- Calculating the percentages of the Battle

well, now i know that my attack of 300.000 points supposes the 10% of the battle, so now i ask myselff  how many points  is the 100% of the battle. with a simply rule of 3 we can now that the 100% is going to be myoffpoints (300.000) x 100 and divided by mypercentage (10).

So the total of the battle was 3.000.000 of points.

3.-Setting how much remains 

In this moment we know how much was my attack (300.000 points) and which percentage of battle is this (10%).

so if the total of the battle is 3.000.000 and 300.000 of them was my 10% then the defensive points  supposes the 90% of battle and 2.700.000 defensive points

in my first hit i lost the 90% of my attack so i killed him the 10% of his defense, so in my first hit i killed the 10% of 2.700.000 points = 270.000 points

finally we can know 2.700.000 of his total defensive points - 270.000 points he lost in my first hit ---->  2.430.000 defensive points remain on target.

.

Finally i have to set 2 points clear:

- This formula works well when the Battle Loss % is less than 99% (98.9% and less). When the Battle Loss % is above 98.9%, it's not precise, but it still means a lot. 

- Nothing in this game is a guarantee, especially when dealing with mathematical algorithms. There are variances, changes and randomness added all the time.

Hope this information could be usefull for all you.

Very nice explanation. I know how to do this but making others understand is my weakness lol

While it's to be applauded writing guides, isn't this really up to each individual set of players to work out for themselves?


This is a strategy game after all and working out and understanding the mechanics is a massive part of the strategy? If we are going to start to post guides on all the important mechanics there will be no difference between the strong players and the weak players, the good leagues and the bad leagues. That isn't necessarily a good goal to me.

Believe it or not there are some major leagues in the top 10 that don't understand how to utilise the mecahnic above.


Everyone has a right to an opinion. No one has a right to their opinion being respected by other if it can't be backed up with rational and logic explanation

I don't believe there is any harm in making the information available, my Lord.


Note that "Nothing in this game is a guarantee, especially when dealing with mathematical algorithms. There are variances, changes and randomness added all the time". 


One should use such guides at their own risk and ultimately figure out their own strategy, based on the already available knowledge.

A game should not be so difficult to play. To use spreadsheets, etc.. takes all of the fun out of the play.

Stormfall was designed to be a challenging game, my Lord. It is now what it should be. It's definitely not for everyone.

I'll add my 2cents. your exemple works because you used one unit type; in this case, paladins. what if the attacking army is made of dragons, necros, warlocks, greatlords... etc... the "calculating the loss ratio" trick isn't that easy anymore.

one would have to calculate loss ratio per unit type.


if that helps, here's your formula simplified:

DefR:  remaing Defense

Off: Offensive value of a unit 

z: number of units loss

n: total units sent


DefR = Off x z² / (n - z)


your calculation works if you run this formula for each unit type ( dragons, necros, warlocks, greatlords, etc...)


in your exemple, with 1000palads sent, 900lost and offensive value of 300pts/palad (since you said your total off was 300.000)

DefR = 300 x (900)² / (1000 - 900) = 2.430.000


so with an army made of several types of units, one would have to calculate the remaing def unit per unit. and add them all to have the total remaing def.


hope that help some...

I wouldn't worry about it, the formula he posted is incorrect anyways.

which one is incorrect mylord, and then which one is the correct ?

im impatient to know right formula

All of the ones posted.  Because of the bias in favor of the larger army just using the amount of offense sent isn't accurate.  None of them accounted for this.
