Corpse Blood

Corpse Blood is a quest item found on Day 3 by both the Bachelor and the Haruspex in their respective routes. The Bachelor must obtain it to complete the main quest "Enemy Unseen", while the Haruspex can choose between obtaining this item or obtaining another infected organ or infected blood for the Bachelor.

It can be retrieved from the corpse in the Cemetery guarded by three Patrolmen. It can be examined under the microscope in Rubin's Prosectorium to progress the quest. This removes it from the Bachelor's inventory.

"This blood must be analyzed, although the current conditions make any thorough analysis impossible. There's a high chance it contains a sample of the harmful microorganism."
