Yes, pets have been apart of Fallout since the beginning. A Death Claw could be over powered, but I assume there will be, as there are in the fallout universe, different kinds of death claws, with varying size, aggression, and intelligence. If there are intelligent Death Claws, I hope I can be one
, otherwise, when I am end game tier, it would be sweet to have an adolescent/teen death claw as a pet.
This could be done many ways, from enchanter based/ whisperer, or even go get a baby and raise that fellah. Like any harder to get companion, I expect and hope for challenging pets, and would love rare pets, but they don't scale so well, and the flamers will cry nerf for anyone that spends the time to get a truly rare one, that has teeth.
Love the idea for randomly dipped animals. I mean some varmints must have slipped in at some point.
