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
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
Get several high levels and Make them follow something such as a dodo, put them in a tall, open building on aggressive and drop wild dinos in the pin to level them up. And when war breaks out, make them follow a tank so they can knock flying people off their tames. (Idea from sl1pg8tor)
Are not affected by oxygen while on your shoulder, so it helps you to find your body if you die because it will be flying right above the water where you died. Also if attacks while on your shoulder, so it can collect bodies for your herbivores, help keep attackers off of you, and can be thrown at Dinos do kill them. There is no reason not to carry one, they are very helpful.
I tamed one of these that was level 30, put it on my shoulder and forgot about it. Until I was attacked by a lvl 22 sarco. I got tossed off a cliff and my little shoulder decoration flew up and eventually killed the sarco by itself!!! Saved my butt
Artifact mass collection - Dimorphadons are accessible to every cave, and every Dimorph can carry an artifact, the Artifact crates don't take long to respawn, so camp there for a little and make sure every player/dino has an artifact on them before leaving the cave, you'll have plenty of artifacts to display and use to summon bosses multiple times from doing each cave just once!
