Writing one serious review:

Solid card, should be a 2 of in any investigator's deck unless you're a dedicated these-hands-are-for-shotguns-only fighter, or Agnes who can't investigate her way out of a paper bag (and who's spells don't work with this action). Even when not being used to cheese the rules it can bring even terribly shrouded locations into acceptable investigation reach which is pretty nifty.

the FAQ bump says everything you need to know about playing this in higher difficulties. For 2r + 1action you get 3 clues off of 1 or 2 shroud locations, with the single token being the only exception. The value of this would be good if it was almost twice as costly on expert, where -4 is the average you're going to pull from the bag. This saves you actions and cards that you will need bumping tests elsewhere.

So stock up on batteries guys.

So, at the time of release in the Dunwich campaign, there's only a handful of cards that this one will apply to:

• Alyssa Graham
• Arcane Initiate
• Blood Pact

... and this card is awesome. It makes Blood Pact actually work. Previously, 1 doom for +3 to a test seemed, well, expensive. This would only leave the 'end of agenda' turn to make use of Blood Pact (when further doom wouldn't hurt).

Now, though, go nuts! Blood Pact all over the place. Just hope that you can draw Moonlight Ritual (or better, already have one) before the agenda advances, and then clear it down.

I really like the gambling nature of this combination. It feels like a Faustian pact. Will I draw Moonlight Ritual? Do I wait one more turn and use Blood Pact one more time, risking Ancient Evils, or do I clear it now and struggle with a test?

Brilliant combo, both thematically, and in play.

This card is generally considered a great card. For almost any deck that can take it, this is one of the first upgrades you can take. It is quite expensive, but it basically gives you a free action/move per turn. When compared to Leo De Luca, its cheaper but less flexible and will not soak damage/horror. But considering that most turns you will be moving, its not really that much less flexible than Leo. For that reason, this is a pretty good card.

But any of these asset type cards have the same drawback, and that's that they aren't worth as much in do or die situations or near the end of the game. If the game is going to be over in 1 or 2 turns, it'd actually be difficult to get value out of Pathfinder. So pathfinder is a value card, but interestingly enough, in Arkham Horror TCG, at the end of the scenario you need tempo rather than value.

• If you have two of these, you can use both on the same test
• However Counter Ritual can only clear one of these
• Permanent cards cannot leave play, so you can't ged rid of the doom by discarding the Bloodletting
• Use Hollow eyes or coffee to spy the mythos deck, to avoid advancing the agenda too early
• Counter spell also works against Ancient Evils
• If the player leaves (defeat or resign), the doom is removed

I played hollow eyes in my caster daisy deck in a 2 seeker game (rex was using the insecticist) and i really like her, for her static boost and ability. Knowing what encouter card is coming and preparing for it can save you.

• Compared to Scrying, activating her is a free action and she does not have charges.
• In multiplayer, you can look at the next encounter card during any player window (if she is not exhausted). So if a player draws an encounter card with a skill test, you can look at the next card. This may be helpful to protect a specific player. However if the player before him does not open a player window, her ability may be wasted for that turn.
• Tr"Ashcan" Pete's smelling salts also work on her.
• Her bonus is a good for Jim Culver's balanced stats, so he saved charges on Rite of Seeking for higher shroud locations
• Her bonus does not help agnes so much, as her is rather low. You can compensate this, with other cards, like Perception, Flashlight, "Look what I found!" or Rise.

Dealing with her doom:

• Moonlight Ritual can remove all doom on her. As a spell, her friend can find it (use Charisma to have both hollow eyes and her friend in play at the same time).
• Her ability does not advance the agenda, so her doom does not matter, if the agenda would advance the next turn anyway.
• If you discard her before the agenda advances, her doom will not matter. However she costs many ressources to play, so this is a waste. Smoking Pipe is a quick way to dispose her or her friend. You can also show her some Forbidden Knowledge to make her run away.
