Effects[edit | edit source]
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 your Damage Resistance.
Notes[edit | edit source]
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.
