I have recently started a Caesar's Legion melee character on hardcoe mode. The cannibal perk is pretty good so If I become hungry I can just feast on the NCR troops I destroy. The health you receive from doing so is pretty low though. Is there any reason to take this perk OUTSIDE of hardcoe Mode? Or is there any way to increase the amount of health it gives by increasing survival or something?

Well, if you were playing an evil character it'd probably be useful to take this perk, since karma is absurdly easy to gain in this game.

What's the point in posting in font like this besides being annoying?

I am sorry, I just thought it would make it easier to read.

Eat corpses to make yourself evil. once you eat 25 bodies you get the Dine and Dash perk. Then you can carry your corpses to feast on them later. If you get the perk to get blood sausage you will never need anything else to eat. Cannibal perk is really only useful for roleplaying and making yourself evil.
