In this guide, you will find out how to complete the Mounted Combat trial in Horizon Forbidden.
You will need to do the Clawstrider Override and mount on the little one. Approach the creature stealthily, hold the override button, and then press the square button to mount.
After that, stay out of the central area as much as possible. You can always open with an r2, and it will knock the opponents down, but you will not get any extra rewards for doing hard. And make sure you save it before every trial. After killing the first one, you need to walk outside but not through the middle. If the mammoth starts getting involved in the fight, he can turn you into a nightmare. Just press r2 from behind to knock it over. After taking them down, your trial will be complete.
