When dropped, it has the same world model as a blood pack, but is weightless and much larger.
Unmarked quest: Blood Brotherhood[edit | edit source]
After the completion of Who Dares Wins, if the Lone Wanderer did not destroy the Citadel, Paladin Tristan asks the player character to kill super mutants and bring back super mutant blood samples so the Brotherhood can research a weapon that could destroy super mutants with ease. These samples can be found on any super mutant killed by the player character, much like ears and fingers on corpses, and can be exchanged with Paladin Tristan in the Citadel's A ring for caps and XP.
