I am sure this has been discussed before, but my search skills are lacking and I couldn't find the information I need.
I am in a game where a fellow player is summoning spirits and using the concealment ability to extreme effect. I know that it's a dice pool modifier to all perception tests and S4 says it works on the astral too. My concerns and what is not very well established is does it work on all forms of technological sight?
What I am referring to is, does it work on echolocation, ultrasound, the radar sensor cyberware, thermographic vision etc. I raise this question because in the shadowrunner's companion page 26 is a little anecdote about a runner who had spirit concealment and a bunch of other stuff on but still got caught because of his RFID tags. So I can assume that the spirit concealment isn't stopping radio waves from being transmitted. If it's not stopping radiowaves, why would it be stopping ultrasound, or radar sensors?
Right now if you guys don't give me any solid rules or clarifiaction the apparent plan is to summon a F7 spirit use concealment and try to be stealthy and basically waltz around any and all missions from here on on being for all intent and purposes totally undetectable. Now we understand that opening doors, starting fights etc, will stop it. But it still seems too OP to me, that this power trumps and nullifies every last bit of technology out there.
So is spirit concealment just that OP? as long as we get one success on our stealth roll we are basically immune to being percieved as long as we don't interact with any physical objects more or less? One last thing. we have access to the corebook, runners companion, street magic, aresnal and augmentation.
