What is the cloaking power of a Zolazin jammer? is it worth having?

Well to help you in future terms, Never get rid of a Mission Module or Builidng, or Artifact.
Same with NPC, except when you get the upgraded version i.e. Shadin Supercomputer = Shadin AI Core = Shadin Hypergrid Core.

ya, I noobly scrapped a stryll transponder once....

You can message dan on ingame support and get it back.

What does that transponder do then?

20 Scan 20 Defense with both 40 scan 40 defense.

+20 scan and defence for 10 space.
I personally would (and did) do that one first, because it is a shorter mission (60 instead of 90, or something like that).

The scanning helps with hacking and planet finding.
The defence hinders people who retaliate.

After you do that, Then focus on the Zolazin/Galviz chain because it gives you extra NPC slots.

I will take your advice!

However, right now focus on the special mission above all else. Save the rewards until you have 5 research planets, then use them to get 30 scientists each.

30 RP/hour is a fair bit, because that's 720 extra per day.
You can complete the mission 10 times too, so that's up to 300 scientists.

The reason I say do it now is it'll take another month or two for it to become naturally available, then you have 4 other missions to go through to re-access it. The first one costs tonnes of artifacts too.

actually thats a mistake its not got a level requirement

Eh? Since when? The majority of the bi-weeklies are ranks 5 or 10. I do not understand why it would suddenly be rank 160.

Some guy must have said 160, that or dan put it there. Because I doubt its 160.

can't I scrapped it when the stryll chain was timed ( the missions at top that expire in 2 weeks), and that was a long time ago.

Wow you were playing back then, darn, you've been playing way longer than i have destroyer43

ya, I went inactive for like 3-4 months

lol i still have these at rank 169 because i don't want to get rid of them forever
