For mobile, when you taming this guy if you felt or getting knocked out by this horse. The taming effectiveness decreases for the next taming to same equus. To make it 100% or whatever to get maximum...
You need to make him unconscious with trunk than try to tame him again you see taming effectiveness is maximum now. It's helpful when you taming this guy high lvl (150+) with rockarrot no bulm. Coz I tried dumb 180 with rockarrot no bulm
To tame one of these creatures, you would need berries or crops. The best is just Rockarrot. Approach one with the feeding item on the last item slot. Feed it and ride it. You'll need to press the action button (E for PC players) for everytime they stopped moving or the icon on the right flashes, prompting you to use it.
To get a 100% taming efficiency on this creature, avoid spamming the buttons and carefully timing your action button. Make sure that your surroundings are clear and there are not too many threats. They often run off into random areas that tends to be near a Giga territory.
They often spawn in large open fields so that is best to look for one. Good luck and have a good one.
I would not recommend taming a high lvl. If you have the resources, by no means go ahead and get him but I found out recently that it takes an absolute butt load of Rockarrots (100 for a lvl 95) to tame him. It took a very long time and in the long run, I didn’t even get him. Not to mention, you have to have extreme focus not to let him buck you off and lose taming progress for that long of a time.
