It you put them on aggressive and perch em on your shoulder, they warn you of any danger with a scream. Usually it’s a diplo or a compy. If it weren’t for my dimo I would’ve died hundreds of times, he once yelled so I left and the next day i went back and say a giga killing a pack of raptors.
I tamed a lvl 15 female one and named it Nova and she was really good. She killed a whole pack of lvl 20 carbonemys without taking any damage and I didn’t do anything except stand there and watch in shock and awe. This is a MUST tame for everyone who reads this. I was only lvl 10 at the time I tamed it and now I’m lvl 40 and this creature has never failed to impress me.
These are amazing in caves and other hard to get through areas where larger dinos don't fit. I have a pack of 10 of these maxed out and never have to worry about being killed in a cave. Unless I'ma dumb and fall into lava or something of course!
