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.

For solo Rita Young this is almost an auto-include. Keeping a hand free for a simple Flashlight or Old Keyring means that taking an Ornate Bow or my fave the Old Hunting Rifle is less practical. Better to one-hand a Meat Cleaver or Fire Extinguisher and run a clue helper in the other hand. So Stunning Blow becomes a super-useful tool to add damage and evade, then recur with Resourceful.

For Rogues that don't have access to Lucky!, this feels like an off-brand version. But note that the condition for playing this card is different: you don't have to fail a skill test in order to play it. That allows the card to fulfill some other roles, too:

• Succeed-by-X: Just like this is a less-good Lucky!, this is also a less-good Daring Maneuver. Sure, for investigators who truly need the effect, just pick up the other card, but deck space is tight in Arkham Horror, or this is just copies 3 and 4 of it. For Survivors, there aren't too many succeed-by cards, but I'd use this for Sharp Vision and Brute Force, two cards which are a real bummer if they don't fire off.

• Token manipulation: You get to reveal an extra token, which you really might want for its own effect; like an or a for the Mystic curse spells -- note that the will be a +2, and it will reveal another token, too (but a won't autofail this time). You could even use Olive McBride to reveal 3 more tokens and resolve 2 of them; both of which will now have positive modifiers! This could also be an interesting way to dig for extra tokens to make Blessing of Isis work. As has already been commented, the taboo'd .35 Winchester will much more reliably get the extra damage now.

In all of these cases, the more tokens you reveal, the more likely to reveal a , so there is some obvious synergy with cards that Seal tokens, but revealing a 0 is also often a waste of time, so you may consider Shards of the Void specifically.

A pretty low potency weakness.

Low movement classes that aren't going to be jumping around the map much anyway like Guardians and Mystics won't really care this is there. Your evasion based rogues or seekers with movement bonuses are going to notice this, but usually just making a simple deck swap (throwing in a painkiller) is enough to get rid of this.

Given that most weaknesses on average make you lose two actions to resolve, this one is pretty weak and is almost trivial.

I'm becoming a fan of this card for my mystic cluevers: play Dayana Esperence, attach Read the Signs to her and now - as long as she has a secret on her - once per round you can play Read the signs for free. Considering the mystics have Enraptured and you test + , you have really good chances to have 4 - 5 uses of this copy of Read the signs.

And considering several good - mystics (Gloria Goldberg, Marie Lambeau, Luke Robinson, ... and Norman Withers) have some access to seeker cards, you can find other ways to recharge the secrets: Truth from Fiction, Eldritch Sophist (+ Forbidden Knowledge or Astounding Revelation.
