You let it latch onto your tames in order to tame it. But reminder! It can’t be a bred tame only “fresh”. So you can tame a dino (ex Carb/Turtle) and feed it to the noglin but you can’t say feed it a bunch of rexs you hatched and raised. Hope this helps and makes some sense!
Because this is the first creature in ark that will be able to mindbend with other dinos, they might create a new way of taming it. Taming sacrifices have been done with the troodon, and it might be the same with the noglin. But does anyone think it would be cool if wildcard DID start to create a new type of taming!?
I'm finding that on servers with higher Wild Dino levels, 5 Brontos are not enough for max efficiency. And since Noglins will eat 5 dinos before they lose efficiency, they are impossible to get max efficiency when taming them.
