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
I had two Mikey and Leo RIP didn’t last long because I’m not a master at what can kill them but the poop throwing things can kill them and a brontosaurus can kill them I don’t know if any others so far but if I find out I’ll keep you updated.
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.
I have seen people saying that small packs of these sky chickens can kill everything. Well, I seen a lvl five rex send at least 7 flying, and a well leveled, tamed dire wolf can Wreck these wimps as long as you’re riding it. The reason they’re so hard to kill for wild creatures is that they run around trying to chase it. So, if you ever run into a small pack of these guys, and don’t wanna tame ALL of them, then a dire wolf, raptor, argent or Sabre (or anything with low stamina drain, or A LOT of stam) with a few levels in health and Melee is a good choice for killing off the bolaed dimorphs comrades. Key point, don’t let your tames fight these guys without you on their saddles.
When in areas that have many dimorphadon remember to be careful and not to hit one by accident when fighting other creatures as you can easily be overwhelmed.your mount will not be able to save you as they deal damage directly to the rider.
These guys can be hard to fight not because they do massive emounts of damage but because they are hard to hit, I had just tamed a carbonymes when I decided to hit on of these guys the murderd my carbonymes and it couldn’t even hit it
If they attack you while your mount depending on what the animal it is, they will counter attack YOU not your mount. I hope you respawn close but you'll find the animals ok unless something else came along.
