An Ounce of Prevention

An Ounce of Prevention is a quest in Fallout 76.

Detailed walkthrough
The player character needs to collect three blood samples from a wolf, a mole rat, and a feral ghoul. Then they need to get a T-type fuse from a nearby hardware store located on the map. It will be in the building marked appropriately. The spots marked on the map are approximate not pin-point locations. When looting the creature, one then needs to choose to obtain a blood sample (such as press "T"); it is not a physical item to collect.

Behind the scenes
The title is a reference to the famous Benjamin Franklin axiom that "an ounce of prevention is worth a pound of cure," meaning that taking small steps to prevent a major problem is easier than dealing with the problem itself.

Bugs
The map marker for the Type-T fuse may focus on an underground tunnel instead of the item. The item can be found in an explosives crate in the eastern storage room of Greg's Mine Supplies.
