This might seem like a one-to-one parallel Dr Milan Christopher, but it's harder to get. Chapter 2 doesn't have as severe an imbalance in economy as before (crack the case has become bounty, and there's no Midnight Oil), but $4 and a slot is still a lot. Seekers can get clues every turn in almost every scenario of the game. Some scenarios have only one enemy, or don't spawn them for a few turns... Or even punish you for killing them with Vengeance. It's still good and a reason to get charisma, but this guy might sit in your hand longer than you'd like.

This is a stone simple, mill your deck and get to the good stuff card. It has a trigger that's going to hit multiple times per game (even if your Guardians are at 100% efficiency, enemies will still spawn). You're trading a card and a dollar for two cards, a trade that gets better and better the more XP you put into your deck.

Pocket Telescope combines well with Professor William Webb. When the connecting location's shroud is lower, use Pocket Telescope, when your current location's shroud is lower, use Professor William Webb's ability instead. You may even be able to combine them to get a clue at your current location when the connecting location's shroud is lower. It's best when there's a nice item you'd like to recur.

Pretty strange basic weakness for an investigator who doesn't have any search mechanic. Joe Diamond isn't especially crazy about Right Tool for the Job anyway. It is also pretty mild and helps you lower the number of cards in your deck if you'll get rid of it just before the end of the scenario. Until then, you are free to cycle the Detective's Intuition like crazy to earn to pay the cost of this one.

Black cat suffers from the fact not all campaigns feature both a tablet and an elder sign token at once in the chaos bag, especially those with branching paths... But if they do have them, the value of the car goes up considerably beyond being just very well-priced soak-per-resource asset, only behind Lita

But I think there is a particular Investigator that makes the cat shine: Hank Samson!

Hank's ability is fairly situational given he is prettty squishy himself, not always present in locations with other Investigators and cannot auto-catch up with them and many allies of his class are made to tank for him. You can get some mileage by having him close to Beat Cop or Grete Wagner or call them back with A Chance Encounter, but that requires another party member and some coordinaation, it's not something Hank can do on his own.

However, with this Hank can more or less use the Black Cat's ability forever! Is the kitty down to the last point of health and sanity? Just take the damage and horror for the feline until you reveal an Elder Sign and fully heal the Black Cat! Even better, if Hank is resolute, he can use this as a controlled source of damage and horror to put on himself to draw cards or gain resources (depending if he is in his "Warden" or "Assistant" from), and if you don't need to heal the cat, you can use Hank's Elder Sign to dump damage or horror on him or something else!

So Hank gets the ability, for 5 exp to get an ally that can basically treat 2 out of 4 of normal symbol tokens as -1 forever basically: honestly, that is a pretty sweet deal in my opinion, at least in standard/hard!
