Besides having an effect that is actually pretty good on its own, this card makes Dynamite Blast much better. It can be used to perfectly position the enemies and keep the investigators out of the blast radius. In some situations it is better than Elusive as a dynamite-enabler, since it can avoid putting your teammates at risk, and because it can move enemies into a location that has other enemies, to group them together. And unlike Elusive, warning shot is in-faction so all who can use the dynamite can use it. The firearm ammo requirement is definitely a limiting factor, since many decks include few or no firearms. But now with .45 Thompson, there are a few options to choose from. It’s also worth noting that it cannot move elite enemies.

I'm not convinced by this card. While there's something nice about turning any main/off-class seeker into Rex for three actions, this card doesn't represent the best value IMO. Including the action to the play the card, this card generates the equivalent of two actions. It costs a whopping four resources to play and will leave the player 3 resources shorter than if they had Dr. Milan in play and investigated them the old fashioned way.

A magnifying glass costs 1 (or 0) resources, is fast and gives the same Int bonus while investigating. Further, Fingerprint Kit loses value and/or utility on 1-clue locations. The net result of playing this card vs not playing it is 4 resources for 2 clues. 3 resources if one played Magnifying Glass instead, 7 resources if you count the resources not gained from Dr. Milan. It doesn't help on 1 clue locations. I think if it cost less, had more charges, or could get more charges it might represent better value.

In fairness, the net two actions could be used to clear out a location in a single turn, otherwise not possible so there's something to be said for it, but it's so costly and not always guaranteed to be useful, unlike a magnifying glass and Dr. Milan. I think adding more charges to it (Venturer, Emergency Cache (3)) will be a massive boon to this card (tho Venturer does itself cost 4 resources and an action to play and can only be used by main/off-class blues).

While this card can be used by guardians as insurance against item destruction on their expensive weapons (lightning gun, timeworn brand), paying the cost of 4 or 5 resources to replay the item could still be problematic ('act of desperation' could mitigate this by giving you resources equal to the item's cost after a successful attack).

A much better use, in my opinion, is to play 'well-maintained' on low-cost and high-value items that are cheap to replay and preferably discard themselves after use. One such item is 'grotesque statue' in the mystic class. Diana Stanley can take both 'well-maintained' and 'grotesque statue'. Once you have a statue in play, the two 'well-maintained' events basically function as extra copies of the statue, so you're functionally playing a Diana deck with 4 copies of 'grotesque statue'! Lola Hayes can take both cards as well, but she needs to be a mystic to trigger the statue and a guardian to trigger 'well-maintained' which might be difficult to achieve consistently.

Out of interest, do we have clarification on when you get the resources ? I read it as being immediate, ie before the test is undertaken. This could be incredibly powerful if so. The synergy with certain cards would be incredible. For example, initiate a test at +2 gain two resources which you then spend for a +3 boost from Streetwise. You just made the test easier by one while not having to spend any resources. Alternatively, what's to stop you from having two of these in play and just ploughing through easy tests getting 2 resources and a card every time ? Agnes can take this and partner it with something like 6th Sense, where she's just investigating at her willpower level every time. This is likely to mean that she sits at 6 or 7 (or 8 with Dark Horse) on a regular basis and she can just plough through any shroud getting 2 resources and a card every time she does it.

I'm not sure I agree that it doesn't suit a Dark Horse build btw. There looks to be an obvious synergy with Fire Axe. Guarantees that you can power up a +4 boost every swing if the resources can be immediately spent. Also, it offers a way for a Dark Horse player to get a quick resource boost if they need to pay for an asset.

This is a great card. If it cost 2xp I'd buy it in a heartbeat. I'm surprised that it's available at level zero. Seems almost like an auto-include for any investigator with access to it who has a reliable way of passing a lot of tests.

Finally, True Grit for sanity; exactly what Guardians have needed since the game released.

But just how good is it really? A deck slot is pretty valuable, and given the array of allies who can provide a similar amount of soak while also providing other effects (and being cheaper, sometimes), it might struggle to find a space. Its other issue is that your allies generally have more sanity but less health than you, so True Grit is still your best choice for the team.

That being said, I think Mark and Zoey are all about this card. They have the least access to high-sanity allies from other classes, so this in-faction soak is a godsend for them. Additionally, Roland could use it to shore up his beleaguered sanity, and Lola might want it for the same reason.
