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!?
You can use Sanguine elixer from a Desmodus to finish up the last 30 percent of the tame. I use 4 Voidwryms and net them so they don't fly away. Then net the noglin (didn't reduce effectiveness for me) with the elixer in your hot bar and go up to it and it should light up ready to use, and bam say hi to your new noglin. Didn't see this anywhere and wanted to share
