A blood sac is a junk item in Fallout 4.


The blood sac (not to be confused with the blood pack) consists of the severed abdomen of a bloodbug, filled to bursting with blood drained from the bloodbug's latest prey. It is a source of antiseptic and fiberglass, possibly as a result of the bloodbug's mutant biochemistry mixed with the blood in its gut.


It is used in crafting Skeeto Spit at chemistry stations.
