Protector of Acadia is a perk in the Fallout 4 add-on Far Harbor.
This perk is given to the Sole Survivor as a reward from DiMA for completing the quest Reformation.
The player character receives +1000 Damage Resistance and Energy Resistance for 30 seconds when their Hit Points fall below 20%.
- The Damage Resistance is possibly bugged, as there is no visible indicator such as the one for Nerd Rage! and checking the equipment tab yields no increase.
- The pop-up text for the perk when acquired indicates that there is a chance that the perk will trigger - not necessarily every time.
