Is it really necessary to make the cards for the Great Crate Commotion require the advanced trait challenges e.g. Zeefaring, Monstrous Anatomy? And if you spend one action to only fail the card challenge, you get nothing and a menace increase?
How about: if you succeed in basic attribute check, you get a crate. If you also succeed the advanced trait check, you get another crate or some ‘rare success’ bonus.
If you want to balance things out, maybe slightly reduce the frequency these cards appear on the deck.
Seems like it’s more efficient to just farm many scrips and spend them for this event in future.
