Invasion was a failure. Planetary defenses were strong enough to ward off your advance You had a 85% chance of success

I had attempted Invasion On this planet. (Don't Worry, this isn't a complaint/whine etc)

My Invasion Attack was 3019.5

-Light Singularity Launcher x8
-Leviathan Rift-Emitter x2
-Vortul Blast Phaser x2
-Psionic Amplifier (60)
-Lazuli Mind Controller x3 (70 Each)
-Dominion Cannon x4
-Crimson Auto-Phaser x2
-Prototype Mech XV
-Combat Analyzer
-37 Tactical Officers

X1.3(Artifacts)
stuff like lazuli mind controllers and psionic amplifiers bonus invasion attack are amplified with artifacts

Planet Invasion Defence was 1193 (Defence + Attck)
---------------------------------------
FORMULA= Your invasion attacked divided by 3 divided by planet total defence.
[(Your Invasion Attack/3)/Planet Defence] Convert to Percentage = Chnce of Success
---------------------------------------
PROOF :
My Case
Planet Def = 1193
Iinvasion attack = 3019.5

[(3019.5/3)/1193] = 0.8436 Therefore 84% chance success (It was 85% i know but close)

Can any high rankers gimme more data? i need the list of your weapons.. thanks

The invasion defence is NOT , Attack + Defence

It's . 0.6 x Attack + Defence

60% Planetary Attack + Defence = Planetary Invasion

Hence

FORMULA= Your invasion attacked divided by 3 divided by planet total defence.
[(Your Invasion Attack/3)/0.6 Planetary Attack + Planetary Defence] Convert to Percentage = Chnce of Success

I think i have now perfected

The invasion defence is NOT , Attack + Defence

It's . 0.6 x Attack + Defence

60% Planetary Attack + Defence = Planetary Invasion

Hence

FORMULA= Your invasion attacked divided by 3 divided by planet total defence.
[(Your Invasion Attack/3)/0.6 Planetary Attack + Planetary Defence] Convert to Percentage = Chnce of Success

Thanks to John Lomacin. He helped me perfect it.

So Attack counts less than Defense? Huff, and I just upgraded all my planets on the idea that they were equal. : (

Defence (Standard.Includes Legion Bonus) : 1000
Attack (Standard.Includes Legion Bonus) : 1000

Invasion Defence is NOT = Attack + Defence (Which is 2000)
Invasion Defence IS = (0.6 x Attack) +Defence (Which is 1600)

It would be 90% yah, it doesnt go above 90% for some reason.

And min is 10%?

LOL They're is actually 0% chance invasion. I should've screenshot it when that happened....

Again, we're back to 0.6 * attack + defense or (0.6 * Attack) + Defense. It makes a huge difference.

Those are the same thing.

:arrow: nomenclature

• PD planetary defence
• PA planetary attack
• %C invasion attempt's chance of success
• AS attacker's strength
• PAD planet's total defence and attack strength

invasion formulas
It is assumed that your actual values already include

• the legion bonus for PD and PA,
• any invasion bonus on both sides,
• artifact multipliers & boosters on both sides as well as
• passive planetary attack and defence values

attack strength (AS) needed
AS = (%C / 100) * 3 * (0.6 * PA + PD)

%chance (%C) wanted (capped at 90%)
%C = ((AS / 3) / (0.6 * PA + PD)) * 100

if you know the attacker's strength: total defence needed
PAD = AS / (3 * (%C / 100))


Remember: there is always a chance of invasion failure
