Shellsnapper Stealth Kill - Horizon Forbidden West

The only thing you will need is one blast trap. At this point, you probably have plenty on you already.

Right after you enter or when you are in the arena, you will need to set up a trap.

After that, wait for him to turn and move up his path a little before shooting down the first trap.

You will deal a massive amount of damage.

You have to speed up, if your aloy is stealth based, at this point you can probably destroy him with a stealth strike.

If not just wait a little bit until he completes the path gets blasted back by the already set up trap.

Then simply take down the second environmental trap and that's it.
