Blood sac (Fallout 4)

A blood sac is a miscellaneous item in Fallout 4.

Characteristics
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.

Locations

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