People haven’t emphasized this enough, but these things do a LOT of damage in the wild too so you need to be really careful while trying to tame them. Specifically the R variant, which I have been taming on Fjordur can just shred through your tames and you. They can also shoot you while your on a mount.
Never underestimate these bastards, I was trying to tame one of them and THEIR NEEDLES HAVE RANGE! I was on the other side of the lake in the desert biome and I was getting aim boted by thier needles. MAKE SURE TO HAVE SOME MED BREWS IF U TRY TO TAME ONE!
