A recent review of Darrell's Kodak reminded me of how insanely well this card synergizes with it. You are "very" (as odds come) likely to essentially get 1 evidence and 1 clue without spending an action. It's even better: You can both pick the best investigator suited for the drawn encounter card AND choose their location for discovering the clue, snatching the just-placed evidence.

That last part really makes me think they designed Nature of the Beast heavily with Darrell Simmons in mind.

Bandages probably does the job as well or better most of the time. You're paying 1 xp for an extra supply (fine, but probably not a priority). You can use this to heal damage that is in play before it comes out, which Bandages can't do, but this can only heal once per turn, and it can only heal yourself/your allies, where Bandages can heal other players and their allies. I could see upgrading Bandages into this late in a campaign when I'm out of other meaningful ways to spend XP, but otherwise I do not think this is likely to make it into my deck.

Quite a bit of potential! If you burn it for the extra clue on the first use, you could read this as a 2-cost Fast event to grab 2 clues. That's twice as good as Working a Hunch, or an actionless "Look what I found!". If you have the time and wherewithal to trigger this multiple times, you could actually get more clues than that out of it, which would be amazing (scenario 2 of Brethren of Ash is a good candidate for this). Just make sure you can reasonably pass either a or test, which shouldn't be too big an ask for most Survivors.

If you don't need the card for the effect, it still commits for two or two (or a or ), which covers a lot of use cases.

Like the venerable Lantern before it, this is a lot like Magnifying Glass for Survivors. Instead of an emergency damage source (or being played fast in the case of MG), the bonus effect on this one is the ability to reroll a failed test once per turn. Not a bad kicker at all if you're just looking to grind out one clue per action. I think I'd usually prefer Nautical Charts for the innate clue compression, but if you're playing a character that's not good at drawing cards, Old Compass be what you want. Synergy with Stella Clark who wants to fail tests anyway; if you fail this test, you get a free reroll AND your bonus action, nice!

A strong enabler for Darrell's Kodak is Dr. William T. Maleson (2). This allows you to manipulate what encounter cards are drawn (for yourself or an ally) to get a treachery that generates evidence, in addition to dropping a clue so that you can gather evidence on your location even if it had zero clues on it before the mythos phase. Another thing to keep in mind is that you don't actually need to be at the locations where the evidence is, just discover clues at them. Shed a Light will let you snap a pic of the enemy your guardian is currently fighting four locations away.

You don't want to rely solely on the Kodak though, as you at best get one evidence per round. Luckily Empirical Hypothesis has got you covered. All three cards are part of the same expansion as Darrell Simmons and are great cards on their own for him.
