Highly recommend trapping in circle of gates. It is completely passive if there is no other members of the same species it transforms into even if it becomes a rex it'll be passive. If you can't do a transformation just wait for it to change back to itself then to another creature tamih effectiveness and % will remain unchanged. It seems to favor turning into.

Paracertherium, Sabertooth, Anky, Procoptodon, Carbonemes, and few other similar creatures. It doesn't seem to turn into flying dinos when wild

Step-by-Step Taming Process

1. Locate the Enigmasaur in Disguise:

• Find a wild Enigmasaur while it is actively mimicking another creature in the wild.

2. Identify the Mimicked Species:

• Watch which creature it has transformed into (for example, a Stegosaurus, Direwolf, or Moschops).

3. Bring Your Own Tamed Match:

• Ride a domesticated version of the exact same creature that the Enigmasaur is currently mimicking.

• Higher-level tames generally yield better taming affinity.

4. Present the Creature:

• Approach the Enigmasaur while mounted on your matching tame so it can scan or drain life/interact with your creature. Keep your distance from aggressive wild dinos that might interrupt the process.

5. Repeat as It Cycles:

• The Enigmasaur will cycle through different creature forms as the taming bar progresses.

• You must repeatedly bring out and ride the matching species for each form it takes until the taming percentage reaches 100%.

• Keep a mobile cryofridge, generator, or a pocket full of cryopods ready so you can quickly swap to different tames without dealing with lengthy cryo-sickness timers.

you can trick wild ones into taking the form of any dino you want by putting it somewhere far away from other dinos then bring a wild dino near it to mimic

Glitched on Official. Don't waste your time. Tired of this.

Maps that have fewer species like scorched earth, lost colony and aberration so its pool of species to scan is less.

So according to the dossier, to tame this on November 6th it will form into different dinosaurs and the dinosaur it forms into it will request for you to show it meaning if it turns into a rex you have to show it a rex

Not a knock out tame, tried failed

Please be a standard knockout tame

This probably won't be a knock out, it'll probably be essentially hide and seek with an item from it but not trackable even with tek helmet. It'll probably be Find it while invisible and feed it. Or some slightly more aggressive Variation of it. All of the Fantastic Tames so far havnt been simple, simplest was Pyromancer. Get it wet, get it low, kill stuff.
