Obviously if you have a lot of time on your hands anything could be used to kill a deathclaw, but....well, switch that out with utah raptor and you see my point. What would *stop* such fallout monsters is a subsection of what *could* kill them. Also, while I'm on the subject I suppose a similar question would be interesting. Namely, given what it canonically takes what does that say about the 'characteristics' of said hostiles. Some of those floaters man. They just love the taste of lead...or depleted uranium if you've got any. I mean are they like superorganisms, and if you kill half of them then the other half is still totally alive or something? Do deathclaws have grade 8 bullet resistant skin or do they just have a lot of useless internal organs for me to rupture? You know, like Zoidberg. Man what a great cameo that would have been for him to be in Surgeon Simulator. Then maybe I would have played it for slightly more than ten minutes.
