Feral ghoul reaver

The  is a type of feral ghoul which appears in the Fallout 3 add-ons Broken Steel, Point Lookout and Fallout: New Vegas.

The reaver wears what appears to be the remains of metal armor and has significantly more HP than any other form of feral ghoul. It is also set apart from other feral ghouls by its unique ability to throw a grenade-like explosive called "radioactive gore", improved speed, and a special effect that emits from its body similar to the glowing one's radiation pulse.

Characteristics
Feral ghoul reavers are really tough enemies, more than twice as durable as sentry bots or deathclaws. The reavers are extremely quick, and their lunge attack can send the player sliding back some distance with every strike. Their blows, like a deathclaw's, tend to pack quite a punch and even high level players are prone to being crippled quickly and killed in short order if not careful. As with all fast melee enemies, the dart gun is highly useful in dealing with reavers. Their radioactive gore easily cripples limbs and is almost always thrown with deadly accuracy. Reavers seem to be highly perceptive as they (unlike deathclaws) can even detect high level players in sneak mode wearing the Chinese stealth armor. The ghoul mask is very helpful as they will not attack you if you are wearing it. Similar to glowing ones, they emit radiation in large quantities.

Locations
Multiple reavers can be found during "Who Dares Wins" in the Presidential Metro and in various places around the Capital Wasteland if the player character is of high enough level.

They can also be found in Point Lookout, most prominently at Turtledove Detention Camp, Jet Crash Site, and Ark & Dove Resting Grounds.

Feral ghoul reavers can appear in Fallout 3 prior to the main quest being completed if the Broken Steel add-on is loaded. Franklin Metro Utility, in particular, will be filled with them at high levels. They can also be found in Taft Tunnels during the Waters of Life quest if the Lone Wanderer is of a high enough level as well as in the Museum of History during the Head of State quest. Several can also be found in the Dunwich Building

They can also be found in Mothership Zeta, in the Cryo Lab, in a room with an alien turret, several aliens, and many cryo pods that contain ghouls and raiders. Some of the ghouls can be reavers.

Fallout: New Vegas
The Feral Ghoul Reaver returns in New Vegas, but is much weaker than its Fallout 3 counterpart. This Reaver is merely a step up from a Feral ghoul roamer, and isn't even as powerful as a Glowing one. However, this is somewhat made up for with the introduction of several additional types of feral ghouls which are more powerful than any of the returning ones, such as the Feral trooper ghouls and the Vault security officers from Vault 34. There is also the unique Vault 34 Overseer, a boss creature who is comparable in health to the original Feral ghoul Reaver.

Bugs

 * Feral ghoul reavers may become invincible for a short period of time. While they can be successfully targeted in V.A.T.S, all shots fired will miss. If this happens, shoot for the legs, or make use of grenades.
 * If a feral ghoul reaver is killed while invincible, their limbs may be stuck in mid-air. Such as when a body clips in a wall, but instead there is nothing there.
 * It is possible to get a split-second appearing message that tells you that radioactive gore can be picked up. The message is the same one as for objects shot out of the Rock-It Launcher.
 * Sometimes when the feral ghoul reavers throw radioactive gore, it won't explode, and will keep throwing it, making them easy to kill.
 * Sometimes when they are throwing their radioactive gore, quickly go into V.A.T.S and target the arm they're throwing it with. Doing so sometimes makes it disapper or get stuck to their hand and they won't throw another one (they'll just run up and attack you, but if hit, you'll feel the effects as if hit by the gore).
