Ghoul Mask

The ghoul mask is a unique piece of headwear in Fallout 3. It is a mask which completely covers the face and appears to consist of multiple patches of feral ghoul skin sewn together.

Gameplay
It provides a Damage Resistance of 3. The primary benefit of wearing this mask is that it keeps feral ghouls friendly to the player and companions.

Although it is stated in-game by Roy Phillips that feral ghouls will attack despite the mask if you stay too close to them for too long, this is not true. You can stand next to them indefinitely, follow them around or even try to talk to them.

Despite the mask being considered headwear, it is counted as a piece of eyewear and not as "full" headwear like the hockey mask. As such, certain headwear can be worn with it. In addition, your helmet does not receive any durability damage while wearing this mask. However, the ghoul mask will take the damage instead and has fairly low item HP, and it will have to be repaired by a merchant.

Location
This unique item may be obtained by completing Tenpenny Tower in favor of Roy Phillips.

Bugs

 * Equipping the mask while it is broken will tell you that you cannot equip broken items. However, you permanently gain the effect of the mask, but if you unequip it you will be unable to equip it again until you repair it.
 * If you enter the tower after the ghouls have taken over, but before speaking to Roy, and if any feral ghouls are killed, Roy will not give you the mask.
