I have loved playing Dr. Caroline Fern for years. This card solves one of her major problems: she needs a lot of assets. She also wants to be able to heal people. But Solemn vow takes deck space, and her HP is low...
This card is useful in a way that Peter Sylvestre isn’t by himself. Its slotlesss but its price compares favorably to Hallowed Chalice, Book of Psalms, or the Meat Cleaver. It doesn’t require the upgrade path of Ancient Stone. (Although you can still take Shrewd Analysis if you want a permanent seeker card to pair with your multi class offerings). Even the art is good for new players, pointing out the rewarding combo of Dr. Fern’s analysis and Agnes’s sanity damaging witchery. A great addition! Unfortunately, it won't trigger Carolyn’s moneymaking talent, or Vincent Lee's ability either. They say “After one of your card effects heals [sanity/damage] from an investigator or an investigator's Ally asset". Sound Advice ain't an ally.
If you’re going to maximize this card, The Star • XVII will let you take more than one damage or horror from other players at a time. Then again, Sound Advice is supposed to require fewer assets from your deck. Tell the rest of the table to dodge the monsters and cancel their treacheries!
