I am a bit surprised there isn't more buzz around this card, more action compression for Survivors is huge. Between this and Sharp Vision (not to mention Resourceful to get them back) survivor is almost as speedy as some Seekers. Darrell's ability to take this, Sharp Vision, Deduction or Deduction(2) and Research Notes gives him silly levels of consistent action compression.
The auto succeed is useful for avoiding nasty token effects and the two extra clues is huge. The difficulty 0 requirement means this is only going to be consistent for investigators using Flashlight or Old Keyring, but that is a lot of survivors and fair number of investigators who splash survivor. With the new Old Keyring(3) this nets 3 clues from a 2 shroud location and 1 clue from somewhere else with auto success! If you aren't using those, you might be Darrell and getting to 0 should not be an issue.
Winging It, Lantern, Cryptographic Cipher, Otherworldly Compass, and Arcane Insight can also lower the shroud, but are secondary options since they only reduce shroud by 1 or you are less likely to have access to them.
This is most useful in 2-3 investigator campaigns where locations are more likely to have 2+ clues on them. Even though you may not profit as often from the extra clue from your location, remotely grabbing a clue off a location with a monster/locked door/high shroud is useful often enough for me to add this to solo Survivors as well.
