Should the player take the Wild Wasteland trait they will be able to craft Fist of the North Rawr instead. Though it has a different name and a separate Form ID, it is otherwise identical to the standard weapon.
Even though Rawr is dark green, the Fist of Rawr is the normal deathclaw color.
Although the game's description of Rawr's Talon says the claw is "noticeably larger than the lesser deathclaws," it is actually smaller than the hand of any variant of Deathclaw.
Rawr's Talon is a quest item, and therefore cannot be dropped or removed from the player's inventory; beginning Dead Money while in possession of it will allow the player to craft the Fist of Rawr in the Sierra Madre.
