The Arena, Machine Reinforcements - Horizon Forbidden West

This challenge is really simple, all you need is a bow that does purgwater damage.

First, you will need to glide onto the platform.

As soon as you land, build up the purgwater status on the ravager.

Right after that, you have to destroy his weapon.

In this state, the ravager is practically useless and he just wanders around the arena.

So you can focus on other machines, it is best to take down the longlex next, you can make him explore if you shoot the blue canisters with shock ammo, but you take him down however you feel comfortable.

Ideally, keep an eye on the ravager and make him reenter the purgwater status. He has one explosive attack by which he can knock you down.

For the burrowers, again you can use any method you want.

You should get knocked out of the platform for some reason, don't worry, and just get back up.

That's the gist of the fight. From this point on, it's just target practice.

And, don't forget to keep an eye on the ravagers' status effect.
