Mounted Combat Trial Guide - Horizon Forbidden West

Your strongest impact damage bow is highly recommended for this trial.

The best place to override the claw strider is in this area, so you don't red alert the tremortusk.

After overriding there, you can freely move towards the first claw strider.

You have to prepare your bow, stop the movement and damage the machine with it.

Number of shots really depends on your damage, the goal is to leave him with as little HP as possible so your clawstrider can finish him off easily (attacks with R1, R2).

As tremortusk will still be in search mode, move towards the second one and use the same tactic as before, and that's it.
