These little guys are great for base Defence. The first technique I mostly only use to defend against quetzals is strapping C4 to a low level dimorph, then whistle him to attack the quetz, and trigger the C-4. Just as he's closing in to bite the quetz. You might need four or five of these guys to down the quetz, but if you ask me, 5 10 minute tames are worth it for a game that probably took the opposition a few hours to tame. Another technique like to use to take out rexes gigas, and other tanky dinos, is go around, behind them with a swarm of dimorphs (don't do this against Brontos or any Dino with a huge AoE attack) Then whistle attack (which is ".") on the rider. They will shred through him so fast, he won't know what even happened. After the rider is off, you can easily trap the giga in a large bear trap, kite it off a cliff (or away from your base) or just kill it, when the Dino doesn't have a rider, it sacrifices attack speed which is a very vital part of PvP.
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.
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.
Tame every one of these you see regardless of level. Up only melee and maybe some health. Once you have 20-30 whistle for them to follow you and attack your target. Hit a rex, bronto, or literally anything that can die once and watch as your hurricane of teeth tears it apart.
Pair a pack of these with a bunch of dilos and you got yourself both land and air superior. You can also bring these with you when you’re riding your Pteranodon on exploration, they will save you and your Pteranodon’s ass when you need to land to regain stamina. They basically dilo but on the sky.
