These little creatures are amazing for clearing caves just get about 20 of them drag them into a cave and watch them work you need to pay attention to there hp though there strength is in numbers so individuals can die
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.
Best tame for the time and narcotics. I have about 20 of these above lvl 200 defend my base.. They shred people along with my turrets. I also raid with 10+ of them. They make shooting at me impossible as they swarm people not their mounts. Use the spyglass to scope dinos or people and whistle attack target. It is an invaluable sniper tool.
P.S. Keep them close to your fabricator and smithy to level faster.
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 had a pack of 15, roughly level 220+ mostly second generation beasts. All at 2500ish health and 300+% melee damage. They'd kill wild 150 rexes and brontos in a couple seconds. They're all now rip when I thought they'd work on a level 15 giga... woops.
Highly underestimated tame, great damage potential. Keep on your shoulder and triple your damage factor whilst riding Pter others. Also will attack close range targets so you don't whack your dinosaur on accident. Also, can load excess weight onto it because 50% conversion rate to your carry weight
