Invasion Chance:

(attack+100*konqul*foci*obelisk*amp)=n
n+(n*.07) = Invasion Attack

(attack/.3+defense/.15)*legion bonus+invasion defence)*3 = Total Invasion Defence

Invasion Attack > Total Invasion Defence = 90% Chance

Is this correct? The main bit I'm wondering over is the invasion defence, I'm not entirely sure how that works despite numerous threads.

There ya go.

I see, so the first bit was just changing out the words for numbers. Helps I guess.
I forgot about non Atmospheric Decimator added invasion attack, such as the Prototype Mech XV.
Also forgot about having two Atmospheric decimators, I merely have one.
So I was right I got the invasion defence wrong, the bonus is before the legion bonus.
The last bit being a minor error.
Overall you've been a great help, thanks.

The planet's attack and defense aren't /.3 and /.15, but *.7 and *.85

Also, the invasion chance is the invasion attack/invasion defense, so you only need:

.9 * invasion attack >= invasion defense = 90% invasion chance

Oh ok that makes sense


This went over my head a bit, I think I knwo what you mean but I'll come back to it when it's not ten o'clock at night and figure it out.

Thanks for your help.

Saying that if the planet defenses total 10k after all is calculated, then having 9k invasion attack gives the 90% chance of successful invade. Having 9.5k attack or anything above that still only yields 90% chance.

i thought the equation was more complicated that attack/def capped at 90

Good lord you guys are mucking up what is arguably the most well known DanMath equation...

Standard Attack = (Attack from mods+Attack from TOs) x 1.20 (if Konqul) x 1.05 (crystal) x 1.10 (obelisk) x 1.10 (crux) x 1.15 (crimamp) x 1.08 (UST buff) NOTE: If you are Konqul, the 1.20 multiplier is already added to the Attack stat on your ship tab.

Invasion Only Attack = IOA from mods x 1.20 (if Konqul)

Total Invasion Attack = (Standard Attack + Invasion Only Attack) x 1.07^n, where n=number of decimators.

Total Invasion Defense = (Planet Defense (x .85 with Storm Charge) + Planet Attack (x .7 with OMD) + Invasion Defense Stuctures) x (1 + Legion Bonus decimal)

Chance = TIA / (3 * TID) max of .90


In other words, multiply your Ship Attack by all your individual attack buffs. Add stats that are listed as Invasion Attack (multiplied by 1.2 if you are Konqul). Multiply THAT total by 1.07 for each decimator you have. Divide that total by 3x the TOTAL invasion defense. That gives you your chance to succeed capped at 90%. Really, if you write your sh!t down, it's a fairly easy and not complicated calculation. I don't get why people are STILL having problems with it.

What are you talking about? We have all of that. Although that is a good note, that the Konqul bonus is already included.

You're the one glimmer of clarity in that mess, Ferrus.

I wonder if people might still be getting confused because of the 3x multiplier. You can divide Invasion Attack by 3 OR multiply Invasion Defense by 3 in the chance formula. Either way, you get the same results. Problem is when people include the 3x multiplier when they say Invasion Attack or Invasion Defense. Regardless of which way one decides to calculate the % chance, that 3x should not be incorporated in determining either InvAtt or InvDef. It is completely separate from them and is only included in the chance formula.

I suppose you could argue that, but he included it in the invasion defense, so as long as we all word it as such in this thread there is no problem. Of course, not all discussions include it that way, so I agree that that is a problem in general.

Thanks Darth as always, and the reason I wrote this thread is because I'm beginning to take notes about near everything, so naturally my invasion chances was one of them. However I don't see where yours differs incredibly with anyone else's equations, if a little better set out.

It just kinda peeves me when people mix equations. Keeping things consistent makes it easier for everyone to follow. For example, if someone includes the 3x in calculating the invasion defense and someone else takes that number and RE-MULTIPLIES by 3x because that's the formula THEY use... Well, I'm sure you can see the problem...

Yeah I get it, well I know how it works now so thank you again, to everyone for their help.

Honestly, I just triple the planet's Inv Def and divide my attack by it. Multiply it by 100, problem solved.

That doesn't take into account invasion attack, either decimator or not, it can make a big difference.

Great info above... you may also wanna think when it said "90% Chance".... can also mean 91%, 93% etc

so as long as formula is close enough, is good enough

None of this matters if the RNG Gods are smiting you. I've failed 3 times in a row on a planet with ZERO def and ZERO att.

True, yesterday i crit failed on a 90% chance.
