One time I was harvesting stone near the mountains and my pal, sumo the sarco, came with me. (mainly because sarcos have good weight.) I ACCIDENTALLY touched one and he called his possy from 30 island over and killed me. When I got back, I found sumo at 75/390 Hp left and decomposing dimorphidon around her. That was the last time I even thought about hitting one.
A tip for beginners:
If you attack these guys with your dinosaur be warned...
Even during riding your Mount, they will kill you first, not your dinosaur…
And they do tons of damage and are not that easy to hit with smaller dinosaurs (small hitbox)
Try to avoid them early game
They are so cute but are very dangerous. I saw a pack of 3 kill a level 20 sarco! They absolutely perfect to have on your side. You can get easy hide and meat from just sitting in your base and letting you dimes go outside and KILL EVERY THING IN SITE
I went to raid a base with 4 buddies, a rex, 3 carnos, and a bronto with a platform saddle and cannons. All we heard was a whistle and i swear about 50 of these little devil's swarmed the whole group, killing everyone in the group and one carno, the turrets shredded everything else, but the rex must have ran off and we never got a death message so its still out there in the jungle.
