DISHONORED Death of the Outsider – Fountain Pen Headshot “Mightier Than The Sword” Achievement / Trophy Guide
Before you can use a Fountain Pen as a weapon in Dishonored Death of the Outsider you have to buy the upgrade in the Black Market.
You can do this in Chapter 2. After you got the upgrade, go back upstairs from the black market and into the building above it.
One of the rooms on the second floor has the Fountain Pen next to the bed. Pick it up and use it on an enemy to get the “Mightier Than The Sword” Achievement / Trophy.
