They spawn in the snow biome and always spawn with 3 Carnos as allies if your on a tame it can make the tame go out of control and you won't be able to control it affects almost all dinos when tamed you can Ally wild Carnos for a short period of time but the roar if used to much will put your Dino to sleep
No offense mobile players, but it's really annoying to try to look for helpful information, and be flooded with that, "please put it on mobile". They took it out probably because of lag, so, just please, stop spamming this stuff.
First day it was released, started a new character made a stone house boat and headed north. Was docked, taming a direwolf. Suddenly it drops from a cliff with 3 carnos. They surrounded my boat and wiped me in three minutes. If you see the buff, gtfo.
