I asked this in the Rogue Trader Forums (cause that's where are game has gone), but… I'm part of a group that's running around in the expanse, and numerous factions in game (including ours) has use of the divination discipline and the augury/divining the future/scrying type stuff that is available. Are there in game methods to mess with other's divinations? I've tried to find something on the forums, but haven't, and I wasn't sure what was in the fluff. I know blanks can work, but I question their effectiveness in preventing divinations as they still act on the future. Help is appreciated, and everything, from the Holy to the Xenos to Sorcery is on the table.
I'm playing an Ordo Hereticus Psyker Interrogator (long, but fun story) who's out in the Expanse working with a RT and his crew. With Eldar factions and Chaos sorcerers, we all have our methods to figure out where stuff that we want is, even though the results are different.
Our DM does a good job of making sure that the divinations aren't freebe info, and they are always cryptic and could be different, since everything is at the time of the divination, not anything else. Its been interesting, but I want to do what I can to disrupt others from checking on us.
