The in-game text that tells me how to undermine an opposing Power reads like this: "Undermine Senator Lavigny-Duval's hold by stealing Lavigny Garrison Supplies from Imperial Supply vessels [...]"

When they say "steal", do they mean "destroy the vessel then collect cargo"? Because if this is the intent, will that not cause me to lose reputation with the Empire major faction? Which would be especially bad because I am currently pledged to another Imperial power.

On the other hand, if I read the instructions literally and employ a hatchbreaker limpet to steal cargo, won't the Imperial vessel attack me if it sees me scooping up the cargo under its nose?

In most or all cases yes. Undermining usually involves murdering ships in enemy territory. Murder is still a crime, as is assault. So you will incur a bounty, become wanted locally, and eventually lose the respect of a major faction you might be undermining.

However, if you undermine in an independent system, you will only incur a local bounty, and a local reputation loss. So if you're concerned about your interstellar standing, undermining independent systems may be the way to go.

  • Additionally, if you undermine a power belonging to the same major faction, you have to steal the goods. You will lose merits for murdering ships belonging to the same major faction.

  • Ok, so undermining is definitely out the window - good for me, I'm not combat-oriented anyway :-)

Check exactly what the in-game info says for undermining that Power in that system. PowerPlay is complicated, and exactly what you can do to undermine a power depends on that power, your power, and the relationship between the two powers.

If you are undermining a power that's affiliated with the same major faction (both empire, for example), then you have to steal the special cargo. Do not kill the ships, as that will cost you merit points.

You can minimize your reputation hit by following ships into their low wake (instead of interdicting), and being sure to only assault them, not murder them.

Since hatch breaker limpets only work on unshielded targets, you're still going to need to fire at the ship until their shields are down, which will get you a small (~200-400Cr) bounty. (I have no idea if you get an assault charge if you find an unshielded ship and fire a hatch breaker limpet at them) In fact, since you're already firing at them, you can also fire any weapon at their cargo hatch, or severely damage them until they drop some cargo (as part of trying to run away from you). Just be careful not to take their hull or power plant down to 0%.

When you earn merits with your major faction allied Power, I think you also gain some reputation with that major faction. With the assaults (and no murders), it should balance out to a net positive reputation increase with the major faction. (but maybe you should try doing only a few of these robberies, turning in the merits, and seeing what the little arrow next to "Empire" looks like in your status panel).

If you find systems where the minor faction in control isn't allied to the major faction you're with, that should help quite a bit with keeping you from earning a negative reputation with your major faction.

Also, many of the Powers have "oppose Expansion" activities that involve special combat zones. If you go in there, join up with the opposing side (right panel, functions), and kill ships, you earn merits (and oppose the expansion), but I don't think you will lose any reputation with any factions (other than the opposing Power, which you're probably already hostile with). Apparently you can only do this against a Power that doesn't have the same major faction alliance as your own, though.

Also, you could always just stick with undermining powers that aren't connected to your major faction...

Always check what the info says for undermining that Power in that system. You can get to that info from the PowerPlay overview (look at power you want to undermine, find the system and click on it) or from the PowerPlay contact at a station in the system.

  • Regarding the "oppose Expansion" activities: From personal experience this does not work as you suggest. For instance, I didn't get any merits (in the form of PP to turn in later on) when I went against Denton Patreus' forces in one of his Military Strike zones. Incidentally, I also didn't lose reputation with the Empire or gain reptutation with one of the local factions. I'm pledged to Aisling Duval, BTW.

  • I just realized that as an Aisling Duval supporter, the only power I can undermine in a combat zone to earn merits is Zachary Hudson. For Denton Patreus undermining works differently, that's why my attempt at earning merits failed. It all boils down to the combination of 1) which power you are pledged to, and 2) which power you want to undermine. To find out how it works for you: Open the overview page of the power you want to undermine. Select the "Expansion" or "Control" tab and read the instructions how to undermine the respective activity of the opposing power.

    @herzbube: Yeah, I think it's a bit more complicated than I described, and I've edited the question to reflect that you really need to look at the in-game PP info for that power and system. Note that you can also get to that info from the PowerPlay contact in a station in the system you want to undermine in. Aug 1, 2015 at 18:00
