This is straightforward quest. Kill Bolter and go back to Dahlia. The closest Bolter feeding ground is right under a light trap, and very close to one safe house. All you need to do is sneak up to the Bolter, kill him, activate the trap, search him and run back to the safe house.
Dahlia's third potion increased the duration that I was invisible to the infected, but it inverted my vision. I'm going to give this one last chance to find an elixir without side-effects.
- Dahlia requires ingredients for her potion
- Take the potion
- Finally! This potion works perfectly and has no side effecs. Not the easiest stuff to make, but it should come in handy.
