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.
- Found occasionally on dead bloodbugs.
- Sometimes found in meat bags.
- Super mutants may carry blood sacs.
