Thought You Died

Thought You Died is a perk in the Fallout: New Vegas add-on Lonesome Road.

Effects
Your storied past has fallen from memory because everyone thought you died. Your Karma is reset, you inflict +10% damage, and for every 100 points of Karma, you gain 10 Health. You are also immune to critical hits. This perk requires you to have good karma.

Bugs
Simply taking the perk gives you the +100 HP bonus, even though your karma has been reset to 0 (needs verification as to whether this is a constant occurrence, as well as if raising karma by 100 or more removes the +100 HP buff and starts at +10 as it should)

If you're at full normal health, eating additional food to heal up the bonus HP will actually subtract HP from the HP Healed from Food statistic.
