Is there a way to tell what % chance you have BEFORE you try to do this? I just spent an insane amount of energy to defeat the guards and then I failed the invasion and it said I only had a 19% chance of invading. Had I known that, I wouldn't have even started to attack it.

If your attack is almost equal to the planets defense + invasion defense, you would have roughly 50% chance of success

So in other words, there is no where on the page that will do this math for you automatically.

No , just try to follow the rule about the 50%.

I will, thanks. Just figured it was somewhere, maybe hidden in a hover-over that I missed. It looks like it is the buffs on the planet (+300 attack, +300 defense) that did me in. Too bad, it was a 2x mega rich, large terrain artifact world. I'll have to see if the person who shared the location will share it again.

Well at least I picked the right planet this time...
