Rare Metal + 80 Infected Blood (Grace only, ×2)

Blood Specimen (Converged) recipe. Grace gets about 20 in all: 9 loose, 10 from the 5 Rare Metal and the one in the gun. The Supply Box doesn't sell it and Leon can't craft it; he sells it for 400 credits a round. Save it for bosses, for The Girl (1 round stuns her on Casual and Standard) and for lines of 3 zombies (Bang for Your Buck).
