You can get a temporary hacking bonus from a sha'din algorithm. So why not a temporary raiding bonus from an artifact? I know there's Avarice of the Scruuge available during Christmas time from the service terminal, which gives a 20% raiding bonus for 8 hours. But that's only in December.

Crewman Fortitude
Improves the morale of your crew, giving a 10% raiding bonus for 24 hours. This effect is immune to removal from other artifacts.
Requires: 400 Medal Points Earned
Cost: 20 Yellow Badges

Is this fair, or should it cost more? Or should it last a shorter amount of time? Should it also cost some dark badges? Anyone have a different idea for its name?

Hacking is easy. With three cipherbots and an algorithm, you have a hacking bonus of 53.1%. The defense enemy players have against hacking is mainly their scan, but their cloak factors in as well. There is a limit to how high a player's cloak and scan can be. You can hack ANYONE. If you have to, you can stack flares and/or clouders until the player is hackable.

But raiding is based on crew. Unlike scan and cloak, there is no limit to the amount of crew someone can have, which is a player's potential and defense. There are no artifacts you can use on an enemy to make them more easily raided. You can only increase your raiding potential. There is no artifact that gives you a temporary raiding bonus. It would make since for there to be, considering how much you can increase your hacking chances.

because we have a permanent ship module
Protean Armory Effect : Raid +7%
Protean Armory Effect : Raid +7%
Protean Armory Effect : Raid +7%

We also have permanent ship modules for hack. Three cipherbots giving 7% hacking each.

But the thing is, there's TEMPORARY buffs for hack, but NOT FOR RAIDING.

Also, you can hit someone with flares and positrons to decrease their hacking defense. But there is no artifact that reduces the raiding defense of a player.

Another idea:

Stun Grenade
Detonates a stun grenade in an enemy ship, disorienting their crew and making them 10% less effective at repelling intruders for 15 minutes. Useable on higher ranks who have badged or hit you with artifacts in the past 24 hours. Also useable on anyone who has attempted an invasion on a planet of yours in the past 24 hours. Cannot be stacked.
Requires: 400 Medal Points Earned
Cost: 5 Yellow Badges

We already have artifacts that give a static raid bonus

I agree completely, this would be a nice addition to the game.
Though personally, i'd change the name and description, "Stun Grenade" sounds so normal and boring to me.
Try something like... The Attero Device. (CR)
This Ancient device Uses focused Micro-Pulses to Confuse and Disorient living creatures, by detecting and scrambling their brainwaves(or something). If you launch this device close to an enemy ship, it will weaken the crew, rendering them 10% less effective at repelling intruders for 15 minutes. Cannot be stacked.

Could make a nice drop from a new NPC.

Should it be something purchaseable with yellows, purchaseable with dark badges, or dropped from a rare npc?

Ok, let me get this straight... Y'all can use Inhibitors and KrioTorps to make my shields useless, DBombs so my guns are worthless, and EMPs to give my hull the integrity of dollar store aluminum foil. Now you want to take away any advantage I still have left after Proteans that I get from having a big crew? Am I about right on that then?

Yes, exactly. What do you really think of the idea?

My idea is for the artifact to make a ship less effective at repelling intruders, but not less effective at performing raids. This artifact would give players a better chance against higher ranks. And like I said, not stackable.

Um.... Proteans give the RAIDER a bonus when raiding. That reduces the RAIDED's effectiveness at defending against a raid. I've got over 25k total crew. Even at 10% non-stacking, 1 Stooge grenade is going to be BIG. How long does it take to gain 2500 crew?

Then how about 5% less effective at repelling raids? The effect would be removed by a containment cage or when the player repairs their ship. Unlike emp's, bombs, flares, and clouders, it would have limitations in place so it's not overpowered.

What if a higher rank steals a planet and I'm unable to raid them, even with my proteans? What if I multi-raid a lower rank for the fun of it and they're unable to raid me in return, even with proteans?

Then why should I bother making my ship strong?

With selective artifact use, you can turn my fully armed, fully defended, fully shielded, all-seeing, John Cena mobile battle fortress into a rubber dinghy full of blind people with "here I am" signs on their backs. Taking away any remaining advantage due to crew size is like pushing those blind people overboard.

hack them...go for a critical and maybe get lucky with on of their good planets and steal that.
alert them so higher ranks can help raid them.

so you can't raid everyone, big deal get over it and figure out another way to get revenge.

Even if this artifact were added, I still wouldn't be able to raid everyone. And if someone raids me, I want to return the favor, YELLOW FOR YELLOW. And players don't always respond to a legion alert. And when someone steals a planet from me, I prefer to zero ther hacks AND RAIDS, by myself. But I'll sometimes alert a thief when they have a million actions left.

To quote Darth Flagitious from another thread:

While it would be nice if I couldn't get hit by another debuff, I do see the point of the suggestion - we have buffs and debuffs for all the other activities, why not raids? I'm hoping it doesn't get added, but it's certainly a logical addition to the array of buffs and debuffs we already have.

even though i am on the raids leaderboard (as is both Littlefluffy and Plagueis), i don't see the need for a raid buff. raid is based on crew. you collect more crew, you deserve the benefit. there are only a few modules that give a raid benefit and i like it that way.

What can I say your idea is terrible, work harder to make your ship stronger. Those you can't raid are stronger for a reason, and diminishing their work so you can feel better about your ship is not a good enough reason for Dan to waste time making this crappy little artifact.

I could insult, you and your legion and do it in less than the time it takes me to burn my energy pvping and dumping my resources, but you are not worth the effort.

Thank you for pointing that out! I just looked at the leaderboard and noticed that I dropped about 7 or 8 places since starting my progress on restraining order. But I haven't dropped much at all on the hacks leaderboard.
