Cannibal

Cannibal is a Fallout 3 and Fallout: New Vegas perk that allows the player to engage in cannibalism.

Effects
In Fallout: New Vegas, the perk functions the same as it did in Fallout 3, except that it can be acquired much earlier (at level 4 instead of level 12). After consuming 25 corpses, the player will acquire the Dine and Dash challenge perk, allowing them to harvest human remains, rather than eat the corpse directly.

The player can only eat corpses of humans and non-feral ghouls. In Old World Blues the player can also eat the corpses trapped inside Y-17 trauma override harnesses.

Each corpse restores 25 HP, adds 3 rads, and reduces Karma by one point. Each corpse can only be fed from once.

If the player is caught devouring a corpse, friendly non-player characters (excluding companions) will turn hostile.
