This card has an unexpected synergy for an investigator who came out years earlier. Jim Culver, musician, can use this spell to great effect. His power lets him to treat the elder sign as a skull, and skulls as +0. But that’s different than the token.

So when Jim puts Flame into play, he’s only afraid if he draws an actual zero (on hard or expert, there aren’t any +1s in the bag.)

This makes it much better for him than shriveling, which can trigger off during a skull token even if it counts as a zero.

LivefromBenefitSt's review of the first Law of this set pretty much sums up why this might be the most annoying Treacheries in the game.

Fun fact for this particular card is that, if I'm not mistaken, this is the first instance of an effect that fundamentally changes the game depending on the language you are playing (card titles differ in word length in different languages). So for example Look what I found! is playable while you hold Pandemonium and can be discarded to get rid of it if you are playing the game in English; while it's the opposite (dead card in hand) if you are playing in Spanish ("¡Mira lo que he encontrado!").

This is a question as opposed to a review: suppose an investigator controlled the custodian and then lost control of it in Act 3a. Then for the purpose of Act 2b (and the scenario resolution), is it true that the investigator "has performed" the "An investigator controls the Custodian?"

To be clear, I think this is different from Act 2a, where it states "if three of the following are true..." and when you lose control, it is no longer true that you "have control". However, given the way the game resolves the number of tasks in the resolution of the scenario, it seems it expects the number of tasks you have "performed by the time the scenario ends" (as opposed to, say "to be true by the time the scenario ends") to be definitely between 3 and 6, and you can get into a state where you only have 2 tasks (by doing the Custodian and 2 other tasks, then losing the custodian), which is not given a consequence in the resolution.

Extremely nice Ally for our girl Agnes Baker

She once had an addiction to Painkillers, though hard to manage, she figured out that a Summoned ally would make her problems disappear.

Same 3 health, although more damage and an investigating ability.

The way to put the dog in play is somewhat complex to manage: You either discard it reaching over your hand limit or discard it via Scroll of Prophecies. Then put it into play using A Chance Encounter.

Dealing with weakness was too hard on Expert difficulty.

Blood Pact will help deal with tougher enemies.

Since this card's text was errata'd to match Summoned Hound, there now exists a way to "cheat" this into play without adding its Guardian weakness: Archaic Glyphs (Markings of Isis). Rex Murphy, Ursula Downs, rogue-classed Mandy Thompson, Lola Hayes, and the upcoming Monterey Jack all have access to this combo.
