This card will see very little use because of the high XP cost and the fact that it uses an arcane slot. It can be searched with Arcane Initiate, discounted by Uncage the Soul, gets a bonus charge from Akachi Onyele, and can be returned to play again with Spirit-Speaker. It synergizes with The Chthonian Stone but not with most of the other cards that refer to chaos tokens. I guess this card is best on easy mode where you don't need powerful cards like Shrivelling (which costs the same XP and arcane slot!) and you only fail skill tests when the auto-fail token comes up. But that's not a fun way to play, in my opinion.
Seal of the Seventh Sign
Over the Threshold and Beyond
Seal (). Uses (7 charges). If Seal of the Seventh Sign has no charges, or if it leaves play, remove it from the game.
Forced - After a , , , or token is revealed during any skill test: Remove 1 charge from Seal of the Seventh Sign.
Circumstance: 2-4 players. Somebody else has promised me that I don't need Shrivelling, so I just focus on the clues! This means that I have 2 unused arcane slots.
Slot 1: Protective Incantation, sealing a , or .
Slot 2: Seal of the Seventh Sign.
I generate resources with Dr. Milan Christopher and my cards are cheap thanks to my ability, so money is not a problem for me, and even when the Seal of the Seventh Sign runs its course, ill have cash enough and the draw speed to play the other one right away, or just fill the slot with the other Protective Incantation.
P.S. Even if I'm not around I still think Seal of the Seventh Sign is quite good, it's great on easier difficulties where the largest penalties are lower and easier to cover, the freedom to just brute through every check with no chance is tremendous, the main question to ask before you add it is: how much do you need your arcane slots? For most characters the answer is "Dedicated to Shrivelling and Rite of Seeking exclusively".
P.S.P.S. Silly of me, I am becoming forgetful with age. I especially like to bring my Seal of the Seventh Sign in Dunwich, where we the investigators may affect the token pool!
Can Akachi Onyele use Spirit-Speaker take Seal of the Seventh Sign back to her hand or does that trigger the "If Seal of the Seventh Sign has no charges, or if it leaves play, remove it from the game." effect?
