Perks: Level 12
Cannibal (1 Rank)

With the cannibal perk, when you're in sneak mode, you gain the option to eat a corpse to regain health. But every time you feed, you lose karma, and if the act is witnessed, it is considered a crime against nature.

Our grade: D. There are lots of ways to regain health, and this method ranks way down there with drinking out of irradiated toilets. But it might be fun if you're playing an evil character.

Fast Metabolism (1 Rank)

With fast metabolism, you gain a 20% health bonus when using stimpaks.

Our grade: F. You can just use 20% more (easily obtainable) stimpaks.

Life Giver (1 Rank)

With this perk, you gain an additional 30 hit points. Requires EN 6.

Our grade: C. This perk gives 10 more hit points than adding a point to endurance, but it's probably only useful to characters specializing in melee or unarmed combat.

Pyromaniac (1 Rank)

With the pyromaniac perk, you do +50% damage with fire-based weapons, such as the flamer and shishkebab. Requires explosives 60.

Our grade: B. This perk also works with Nuka Grenades and a few other fire weapons. If you get any such weapons, and you like them, then this perk is well worth selecting.

Robotics Expert (1 Rank)

With this perk, you do an additional 25% damage to any robot. Even better, sneaking up on a hostile robot undetected and activating it will put that robot into a permanent shutdown state. Requires science 50.

Our grade: B-. You'll face off against some tough robots in the latter half of the campaign, making this perk useful at times. You'll also receive some extra dialogue options if you have it.

Silent Running (1 Rank)

With the silent running perk, you gain an additional 10 points to Sneak, and running no longer factors into a successful sneak attempt. Requires AG 6, sneak 50.

Our grade: B+. This perk means you can run while sneaking, making it a great bonus for sneaky characters.

Sniper (1 Rank)

With this perk, your chance to hit an opponent's head in V.A.T.S. is significantly increased. Requires PE 6, AG 6.

Our grade: A. Since you're probably going to aim for the head most of the time anyway, it's good to have extra accuracy.
