This stinking thing!!! So annoying!!! I was taming it on a cliff and I was a bit slow and it knocked me off. RIGHT INTO A SWAMP. I swear, while everything was eating me, sarcophagus, titanoboa and mega parana, I saw it laughing at me.
Well the Equus is a hard tame,even a t-rex is easier but you will need around 30-60 carrots so to get that you will have to plant some get a medium plant crop and in order to the seeds go to the nearest forest and keep gathering plants until you get the seeds plant the seeds with fertilizer inside the plant crops.
Taming a equus is a passive tame not a knock out. You'll need to make a trap so it won't run off and get killed. You'll need as much berries as the DeX says. And have a ghillie suit to not spook it.But in case you accidently mount off and lose some taming effect have some more berries with you just in case. This is how I did it.
Quick tip: I was trying to tame one at my house and it bucked me off and my other tames thought it was hurting me so they killed it. Long story short, put all your other tames on passive if you want to tame it at your house.
You can feed it then use a bola (which doesn’t lower effectiveness) and after that use fence foundations and walls to keep it in place and ride it for the duration of the tame. No need for it to run around randomly.
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.
These guys are easy to tame low level but a 150! The tame percentage drops as the horse runs do good luck ever taming a high level one. Unless! You knock it out build a box around it wait for it to wake up and the tame to your hearts content.
