The person who scans your planet may very well not be the person who takes your planet. Ergo, this device.

If someone scans your world, unless they and they alone can take it, you have 24 hours to flux it or improve it's defenses. This is a big thing. Planets are sold all the time, and alerted to legions all the time.

Sure, if a big hitter finds your world all may be lost, but the chances of a big hitter finding your world are slim. The chances that someone will find your world, and alert or give it to a big hitter, are much better.

Do you get a message popup if you set this trap off on a planet you scan ?

From the wording on the devise, I would think not.

It doesn't indicate that you get any kind of warning that you triggered someone's trap.

so then is it just like, surprise! you can't alert this planet! and it'll probably be fluxed within 24 hours too! hahah

If you go to alert a planet you just scanned and you can't, tap it.

If someone doesn't have any proper fluxes, just temporal fluxes they can't flux it.

yeah, ha ha.

i would like to see this races ability as a ability to create rare artifacts like the Adaptive Spire, Ensconcing Field or Pathway Detector (having the ability to make either one) (and, maybe, any further artifacts from this mission chain could be added too) , uses one or more other artifacts to create, with a 40 hour cool down.

the trap lasts a year, but once tripped, that's it. no more trap so you would have to reset the trap to be effective again..... or did i miss a change in how traps work?

yeah that seems to be it, so with a high cloak, temp fluxes and flux probes it is a great addition "i think" to planet protectability.
