Get the ascendant bow you get from dilophosaurus quest

Craft arrows around 20 for around 100 level one

And spam it on that thing while running.

I'm level 33 and killed around 15 of them

Btw I'm on brutual so I have used a lot of points on meele(200%) so I did 450 DMG per hit

I've used most of my points on meele so my health is still 100 and stamina is 150

Im quite unsatisfied with stamina but for that much meele it's worth it
