Stem

"You can barely notice it, just wear a scarf or something."

Stem is a basic negotiation Bog-Parasite card for Rook. It has the effect: "When this card is drawn, increase the cost of a random card in your hand until the end of this turn. Unplayable. Parasite. Hatch."

Stem is obtained, together with Twig, at the start of day 2, as Rook.
