For full Unicorn taming details, get the taming calculator app.
To tame the Unicorn, you must mount it immediately after the first feeding. Tap the action button each time you're prompted to feed again. Reminder for Mobile players: Your Dododex taming multiplier should always be set to 1.75x for ARK Mobile. Use 17.5x for Soothing Balm.
I encountered one on Ragnarok, freaked out tamed it and was happily riding it back to my base when a stupid Raptor decided "I'm about to ruin this man's career" and killed my Unicorn. I have yet to find another one and I have a gravestone for my lost Charlie.
we all know that unicorn can’t eat carrots in mobile and we must have griffin kibble. We can also pick it up with argy. The thing is it won’t despawn if u give it a soothing balm. HOWEVER DONT GO INTO CAVES. When you go into a cave, spawns resets. I gave it a 10x soothing balm and then it despawned with it.
If it won’t allow you to feed it, knock it out and let it wake up then try again. Most likely due to the fact someone else tried to tame it before. Also, it tells you when to feed it at the bottom corner of your screen. PLEASE UP THIS
