- In response to "Can you boost a stat that isn't being tested?": "There is nothing stopping you from using Scrapper or any other similar asset during a test of another type (i.e. it doesn't say 'During an agility test' or anything like that). You may use it during a willpower or intellect test if you wish."
Item. Tool. Illicit.
Uses (3 supplies). If Lockpicks has no supplies, discard it.
Exhaust Lockpicks: Investigate. Add your value to your skill value for this investigation. If you do not succeed by at least 2, remove 1 supply from Lockpicks.

Cthulhu forgive me my sins, but this must be said:
Move over Flashlight! there's a new king in town. Lockpicks allow Rogues to investigate locations at an insane base skill value of + (or other skill value, in certain cases). This is a really nice benefit, but to really illustrate the point consider the following comparison:
Flashlight is a strongly considered item in Expert because of the abundance of high-negative number modifiers that may pop up. While flashlight doesn't modify your base number significantly, for 2 shroud (or less) locations using flashlight lets you auto-succeed any non- token pull. If Wendy or Skids use lockpicks on a two-shroud location they are also almost guaranteed to succeed, bar a total modifier that is greater than -5!
Of course there are a couple downsides: Lockpicks is marginally more expensive at 3r and 1exp instead of 2r, and flashlight doesn't exhaust allowing you to drain a location very quickly in a low-stress turn. On the upside, however, lockpicks can be used almost indefinitely, depending on how often you're likely to fall below the succeed by 2 requirement. At a minimum they have as many charges as do flashlight, and in the off case you are investigating a non- location you can always use to boost lockpicks using Streetwise.
All-in-all an exceptionally good card who's sole real downside is that it cannot be used consecutively in one turn. While power-investigate turns do happen, with some intelligent forethought these situations can be minimized. A very unique and powerful addition to the Rogue card pool, and recommended as a 2x early upgrade.
Don't get me wrong, Lockpicks are good. It's probably a good idea to buy them as Wendy, Sefina, and "Skids", and even Jenny might consider them.
They're a very welcome addition to the card pool, as the Rogue class previously had a severe dearth of investigation options. With Lockpicks, they at least have something, even if they do have to spend XP for it.
However, a couple things must be said against them. Lockpicks are both expensive and slow. The fact that they exhaust every time you use them is a really hurts. In solo play it's not quite so big a deal as lots of locations only have one clue. But if you're playing with, say, three players and you need to clear a 6-clue location? The once-per-turn limit is going to make Lockpicks extremely slow.
Even more critically, with Lockpicks you're still only getting one clue per action. That's why I think this card is nowhere near as good as something like Rite of Seeking. Being able to pass investigation tests more reliably is good, and that's why I often do run Lockpicks. But a really excellent investigation card would let you get more than one clue per action, and Lockpicks doesn't do that.
Once you hit Expert difficulty, Lockpick's charges will start running out, but on lower difficulties I'd imagine they stay in play for quite a long time.
Since Lockpicks can get you a very large modifier, it can be nice to use Double or Nothing with them as a kind of janky Deduction. This can help alleviate the tempo issue I mentioned earlier.
This question is related to the FAQ question above: If I use Lockpicks, can I commit an agility icon card to the test, even if includes no intellect icons?
Apparently, I need 200 characters. Did I reach it yet?
There's 2 synergy I found
- (Test with Status: 10) Play Finn Edwards or Winifred Habbamock. Use Lola Santiago while holding Lockpicks
- (Test with Status: 9) Play "Skids" O'Toole. Use Lockpicks with Reliable
- Other Rogue can use this combo but not so effective as above
This would allow rogue to get clue recursively.
If investigating Arkham Woods, I assume Lockpicks would essentially double your skill value for the investigation test? Admittedly for this location it’s overkill with most Rogues’ evade values, but it’s useful for clarification.
I have found a "sour spot" (the opposite of sweet spot) while using this powerful card. It is on investigator with 3 (Skids), with no other gentle boosts available in the deck, and having to work on 2 shroud location with something like 3 clues. Basic investigation with 3 struggles against 2 shroud especially you want to repeatedly succeed, and also using Lockpicks is slow to drain the location since it exhausts. It is like you are given a bazooka but was tasked to kill some birds.
You will have to intentionally find a more difficult location with 1 to make the best use of your action. And therefore replacing starting 2x Flashlight into 2x Lockpicks may not always be a good idea, regarding of flexibility even in Normal difficulty.
