According to the wiki they're about like taming a bronto with the torpor of a theri, which is a good start, but in terms of actully knocking one out I don't know what kinds of supplies I need to bring. Right now I'm eyeballing a 140 in the snow biome and I'm planning on bringing a 127% pump shotgun and 200 shells, but for all I know that could either be more than enough or not nearly enough, any tips?
