I don't like this card, it is such a tempo lost depending on when you draw it, it is just as bad as the big brother,The Tower. I am running a 3 player RTTCU and Rex was unfortunate enough to draw this card. So far, we are on wages of sin, and he has drawn the devil in his starting hand everygame. It is such a hit in a starting set up. It, thankfully,doesn't cost 4, but that's basically still money for an ally, or asset that I just lost. Not to mention the action, and a card i can mulligan off. If you pull this at the end, that would be fine. Most cards are on the field, and I can just commit cards, and play events. I hate seeing this card and if that was the idea then good job.

What about Bob Jenkins?

If you have Moonstone in your hand and Bob Jenkins is another player using his additional action to play an asset from your hand, is he "you"?

It reads "At any time, an investigator at your location may reveal to you the Item assets in their hand. You may take an additional action during your turn, which can only be used to play an Item asset from the hand of an investigator at your location, under their control. (Both investigators may spend resources to pay its cost)."

What do you say? Can Bob Jenkins play Moonstone from your hand?

Mystics are chronically short of actions and resources. Grounded (3) saves on both by being a 0 cost Fast asset.

Imagine a Holy Rosary that doesn't take an accessory slot, costs 0, is Fast, and provides 2 health soak and it's easy to see the value of Grounded (3). For spellcasting purposes, that permanent +1 skill value isn't too dissimilar to the bonus provided by the Rosary, except it doesn't work on treacheries which makes it slightly worse.

It's great for saving you a Relic Hunter if you want that accessory slot for something else. For those of us playing on Expert, or even Hard, stacking this with the Rosary provides a much welcomed boost to the success chance of spells, with the option to boost further using resources to reach "anything but the autofail" thresholds against higher shroud/fight values. On Standard, this means that you can opt to run a different accessory: Heirloom of Hyperborea for Agnes, Lucky Cigarette Case for Dexter, or Empty Vessel for Akachi without giving up that sweet +1 . Base 4 mystics also get a buff as a result since it's much easier for them to make up the difference.

In exchange for giving worse stats than other composures, Grounded comes with an excellent 2/2 spread. Mystics can usually protect it against the mythos with Deny Existence, but it'll blow up on a single spell backlash from Shrivelling or the Azure Flame, so keep that Eldritch Inspiration, Counterspell, or Time Warp handy. If it does get discarded though, most mystics won't have recursion or the draw power to fetch it from discard, so better take a second copy.

Sadly, it doesn't work with Close the Circle or Mind's Eye, both of which would have really liked the skill boost.

Strongly consider including this on all 4 mystics and any mystic that's taken a few trauma on top of their Arcane Research.

I can't help but notice that Edge of the Earth comes with a lot of level 1+ cards that can be upgraded further. This includes a whole Spell suite, like Divination (1) and Divination (4), which are also good with Arcane Research, but then also stuff like On the Trail (1) and On the Trail (3) and Ice Pick (1) and Ice Pick (3), among others. This synergizes with the investigators in this set that have very limited access to their "off-class" level 0 cards, but also seems like an interesting puzzle with Down the Rabbit Hole. Lily Chen can take this card and use it to discount the upgrade from Butterfly Swords (2) to Butterfly Swords (5), and Norman Withers can do the same for Blur (1) to Blur (4), although it will take one of his 5 Mystic Level 0 slots.

But considering the drawback of this card, is it worth it? You'll pay an extra XP just to get the new Level 1 card in your deck, and get refunded that penalty when you upgrade. Net XP, zero. Ideally, you need to have 14 cards to upgrade in a 8-scenario campaign to get the full value here (we'll see how Edge of the Earth's supposedly different campaign structure affects this), so you'd better really want those non-Level 0 upgradable cards. The EOTE investigators don't really have any other options, though, because Lily & Norman don't have that many Level 0 cards that they could take that upgrade into cards of their "off" class. So, frankly, this card anti-synergizes with the investigators in the box. Your only out is to take In the Thick of It and some trauma for three Level 1 cards, but there still aren't going to be enough cards to upgrade. Strange. But it makes me think we'll have future cards that give you an XP bonus for upgrading cards, without this particular drawback, or more ways to start your deck with non-level 0 cards.

Other Mystics & off-class Mystics should consider this card, though, because of the variety of upgrades now available, including in this set. Daisy Walker can get a discount on upgrading Professor William Webb, and take In the Thick of It to get the upgrade for Eon Chart, among other things. And Father Mateo, starting with an extra 5 XP can spread it out across five Level 1 Spells and get a further discount with an Arcane Research or two, or maybe just spend your starting XP on cards you can't upgrade and don't want the penalty on, and use your Down the Rabbit Hole to upgrade Guts and Robes of Endless Night. Up to you!

Am I wrong or does Jury-Rig work like Lucky? It says "during a skill test", so that sounds like after I draw the chaos token, then I could use Jury-Rig if I wanted. Other mid-test cards are Ancient Covenant and "Lucky" Penny and both function before the skill test has finished.

EDIT: It doesn’t work like Lucky. It’s more like Unexpected Courage.
