I use an argy pack to farm alphas/thyla claws/spino sails. When encountering yuty send 5 good argys at it while staying out of range and they will shred it. Watch out for gigas while farming the north. A level 15 giga 2 hit killed an argy with 10k hps.
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.
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
