Rawr resides in a cave in the Divide. His incredible speed, coupled with his devastating claws, make him a dangerous creature to engage. His victims include a NCR soldier named Gleeson, who managed to survive long enough to record a distress beacon requesting assistance. In the message, it is revealed that Rawr can be driven off with flares, as with any other deathclaw. Therefore, it is one of Rawr's weaknesses, as it will scare him for a short period of time.
Rawr can be found in a dark cave just past the Boxwood Hotel roof, near the pipe that has water spewing out of it. Entering the cave triggers a cave-in which will draw Rawr's attention, resulting in it running towards the Courier. The Courier will be trapped in the cave until the second warhead, which will fall with the rubble, is detonated.
If one switches to third-person view, he/she may be able to see the body of a deathclaw inside the cave behind the rock wall to the Courier's left. It is not alive, and does not register on the Courier's compass. As soon as the player has entered far enough into the cave, that body vanishes and Rawr appears a short distance deeper into the cavern.
Rawr's Strength allows him to kill the Courier in two strikes, even if the player is at level 50 and has maximum Endurance.
Occasionally, when sneaking slowly into the cave, the explosion will go off, and Rawr will spawn hostile to the Courier, but will not charge in to attack. Even when Rawr is fired upon and damaged, he will still stay still, as long as the Courier continues to sneak and stays out of Rawr's Perception field.
Rawr cannot be knocked down. If the Ranger Takedown is used on him, he will simply be staggered.
Like all abominations, Rawr is weak to flash bangs and the flare gun, allowing the Courier to keep him in a state of panic by alternating between these weapons.
