The Arena, Tremortusk Tussle - Horizon Forbidden West

At the beginning depending on the tremortusk position, you will need to run behind one of the structures.

Ready your ice storm boltblaster with plasma bolts and sustained burst weapon technique.

You will probably have your weapon loaded.

Once at least one of the claw striders gets near you, you have to use the sustained burst on him.

After the burst kills him, reload right away and then use a smoke bomb.

While the machines are stunned, your technique will replenish.

So you can kill the second clawstrider right away.

After that, switch to the frost bolts, reload and use the smoke bomb again.

Again wait for the technique to replenish and then use it on the tremortusk.

You will need to aim for the blaze sac to make it explore.

After that, run and hide behind the structure on the other side of the arena.

Smoke didn't really work here, but now the goal is to freeze him.

So you have to preasure him with the frost bolts.

After the tremortusk is frozen, switch to drill spikes and activate the valor surge.

And just keep throwing them with overdraw.
