“You've been exposed to Harold's mutation and your skin is now as hard as tree bark. As a result, you've gained a permanent +5% to Damage Resistance.”— in-game description
Barkskin is a perk in Fallout 3 that is rewarded at the end of the Oasis quest if the Lone Wanderer destroys Harold's heart.
Effects[]
The Barkskin perk will increase the player character's Damage Resistance by 5%.
Notes[]
The Fallout 3 Official Game Guide gives this perk's benefit as being +1 Endurance and +10% Damage Resistance. This information was based on an early build of the game, and does not reflect the final version of the perk in the released Fallout 3.
