You find these just about everywhere. Mostly in the tundra in small 2-3 packs. However, you may also find packs of them in the redwood mountains or large grass plains, and of course on carnivore island.
For those who read my rex story (about a rex on the other island and swam back a couple of seconds later and I was killed by a scorpion) This devil killed me the second when I reopened (near forest) I thought they were only in tundra or snow, I guess not :(
I just about had my Griffin Tamed, then this guy came over Lvl 177 killed me and my Griffin. Rip in the chat. Next time if you see one run away or bola in tame it kill it or run away. Very fast. 130 movement speed at least. Likes for the Griffin!!!😭😭😭
I killed one solo at lvl 12. Using a spear and water. Standing next to a body of water, I let it follow me out for a swim, while swimming after me i stabbed it with a spear until it died. I harvested it’s meat underwater.. did no damage to me while it was swimming. I’ve dealt with dilos and raptors in the same way. Make sure there’s nothing in the water that could eat you before trying this method.
If you stumble upon a pack of sabertooths, make sure you have a movement speed of atleast 120%. If you do, run like heck away if you don't have any ranged weapons. If you have a range weapon and have atleast 130% speed, run on top of a rock and shoot the sabre. They die very quickly from any weapon since they have a weak health build.
