Make sure your Social skills for standing increases are all at 5 and have someone run you in their higher level missions, you’ll share their standing increases.
I don’t know of a Blood Raiders Epic Arc that you can do at negative standings, but you could look there.
Lastly, if they have Distribution agents, do those instead of Security. You can get them done faster for the same standing increases.
Enjoy the slog, repairing faction standings sucks, doubly so for pirate factions with fewer options.
Note, the shared is for the corporation only, not faction. Faction standings are not shared with the blood raider faction at all. Not even with the special 16th mission
If not already done, train Diplomacy skill to Level 5 asap… Then train up Criminal Connections skill… Next is Social skill and lastly train up Negotiation skill…
Like @FlyingDisk said, run Distribution missions to get Storyline mission offers… Distribution missions can be completed rather quickly…
Diplomacy Level 5 is another 4% decrease to your negative standings…
Criminal Connections Level 5 is another 4% increase to your standing towards Pirate Agents…
Social Level 5 is another 5% increase to NPC agent, corporation and faction standing increase…
Negotiation Level 5 is another 5% increase in pay for completing agent missions…
Thank you very much for your answers. It seems I have almost completed the task of increasing the stenting.
My base standing towards their parent corporation was -4,4.
Аfter I did the three points written below, my standing became -2.4. At this point, improving standing through level 1 missions doesn’t seem so daunting anymore.
What I did;
All x4 COSMOS missions (which turned out to be very easy, I spent 20 minutes flying)
Level up Criminal Connections to 5
Completing one storyline mission that drops out once every 16 missions
P.S. A thought just occurred to me.
What if, before talking to the COSMOS agents, I’d taken a stimultor that increases my standing bonus when completing missions? Perhaps I’d get more from Trading?
As a heads up, story mission types give different standing boosts.
The “turn in x ore” missions give barely anything.
The “haul this cargo” give a middling amount
And the combat story gives the biggest boost.
Story missions are completely random for which one you get, so all that really matters is figuring out how to run as many level 1 missions as quickly as possible.
Distribution mission have a lower payout but are significantly faster to complete than combat missions, if you use the right ship. The Sunesis is good for low level distro missions, can align in 2.5s with the cargo hold expanded to almost 1500m3.
