Sometimes bosses in Fallout 4 can be pretty overpowered, such was the case with this Deathclaw. During our first encounter the most powerful gun I had, a beefed up Kellog’s Pistol, barely scratched it.
Not accepting defeat I got creative… this is why you need to hoard stuff in RPGs. Incidentally the ensuing chaos made the game glitch pretty hard.
If you want to make your game glitch weirdly the recipe is four bottle cap mines, eight fragmentation mines, two cryo mines and a pulse mine for good measure. Enjoy!
