Wendy Adams can easily ruin the game from scenario 2 with FOUR EXP. 1XP for 3* easy mark and 3XP for this card. Assuming you get two keep faith and an easy mark in your hand at the start of your round, and your deck consists of 2 easy marks on top and a watchful peace at bottom. Your amulet is in play. This situation can easily be reached by drawing 3 cards per round, and discard everything else at upkeep phase. The you rearrange your deck with your amulet when it's almost empty.

Action 0: Spend 4 resources, place both keep faith on the bottom, add 8 bless. Action 1: Play easy mark, get 6 resource and draw a peaceful watch, while placing 3 easy marks on the bottom. Action 2&3: Draw two cards, both being keep faith. Upkeep: Draw one card, which is easy mark. Mythos phase: Play a peaceful watch, and now your hand and deck is identical to the previous round, so you just loop forever. Plus: You can do something else if you get more actions from Leo or Haste, and more resources and cards from DT and take heart.

In fact, this card is rarely used in our group because it destroys the fun of playing AHLCG. The game is boring when you break it. This deck also requires no thinking at all while playing. Just drawing drawing and drawing and then looping looping and looping.

The ultimate boring game is to combine a Wendy skipping every encounter cards to a Baker removing every doom. That gives everyone else infinite actions and resources, lol.

A signature weakness tailored to the investigator. Looking at the two elements, the effect and the discard condition, we get:

The effect: Draw a card from underneath Gloria and play it as a peril and with disadvantages to dealing with it. Considering that you are unlikely to put cards under Gloria unless you have Ruth Westmacott in play (and that will require Charisma, since Alyssa Graham is so much better), this is almost certainly a dead draw, unless you are trying to keep encounter cards from a reshuffle.

The discard condition: Have it trigger an affect when drawn. Otherwise, it is getting shuffled back to provided more dead draw.

All in all, this is a way below average signature weakness, more annoying than dangerous.

Everyone seems to think that this is a weak-ass weakness, and everyone is right. Looking at the two elements, the effect and the discard condition, we get:

The effect: Winifred gets a -1 to all tests until she fails one. This might mess up some "succeed by 2 cards, but Winifred tends to over commit something fierce.

The discard condition: Fail a test with this committed.

All in all, this is a way below average signature weakness, maybe the weakest in the game. It's not all that likely to hurt her success, and every Arkham investigator fails now and again. It's pretty hard to imagine a less impactful signature weakness, a mere roadbump on the way to whatever Winifred wants to do.

This is a very situational signature weakness. Looking at the two elements, the effect and the discard condition, we get:

The effect: Diana has to discard cards beneath her (reducing her and invalidating the Twilight Blade and her effect, otherwise, she has to take horror. The latter is somewhat fraught, as Diana is pretty average on Sanity, especially compared to other investigators. This can be bad, if you are playing a Diana who cares about or utterly irrelevant if you aren't. The horror cannot cancelled, but it can still be negated by Deny Existence.

The discard condition: One and done, unless the weakness will have no effect, in which case it gets reshuffled.

All in all, this is a below average signature weakness, way below if you have a Deny Existence in hand or don't care all that much about Diana's . Edit: if you really care about Diana's , this weakness's threat gets upgraded, although, as long as you can keep a Deny Existence in hand, it's extremely manageable.

A flavorful signature weakness. Looking at the two elements, the effect and the discard condition, we get:

The effect: Ready enemies at Finn's location or a connecting location. Hunters within one location move towards Finn. Note that they do not engage or attack at this time, so, if it gets drawn in upkeep, Finn has a whole turn to deal with the fallout. Mostly, this gets reshuffled, which is annoying, but hardly scenario-ending. Once in a while, it can trigger in-turn and leave Finn vulnerable to a lot of attacks in the Enemy Phase, but it mostly sets him up to do more evading, which is Finn's bread and butter. Heck, if he has Pickpocketing (2), Finn might welcome this.

The discard condition: One and done, unless it has no effect, in which case it goes back into the deck to try again.

All in all, this is a below average signature weakness, mostly because it keeps getting reshuffled until it hurts you. It might even be way below, in scenarios without many hunters. Edit: This weakness probably gets upgraded in 4-player, as more enemies mean more trouble for Finn.
