The Witcher 3: 10 Hardest Boss Battles You MUST Find

Let's be honest, spiders are horrible. Giant, acid spitting spiders with crab claws however, are a guaranteed one way ticket to a medieval therapist.

As an Arachas, Harrisi has all these grisly, anti Witcher features and then some. As an Arachas boss fight, she (He? It?) is easily one of the most difficult monsters Geralt will have to deal with.

Featured as part of the "Missing Brother" contract, You'll have to delve into an old mine in the middle of Velen for this one. Lucky you.

Once there, you'll discover the grisly remains of Harrisi's victims... as well as some of her delightful offspring.

Taking on both Harrisi and her brood is what makes this fight especially tough, and Harrisi's poison cloud is even effective against Geralt's Quen sign, meaning you'll have to be especially on your guard. If not, you'll be staring at that after death loading screen very quickly indeed.

This fight rewards those who've prepared properly, so make sure to pack plenty of insectoid oil and anti-poison potions, and you should be able to scrape through despite the cramped cave you have to fight in.

Funny that, seems twirling around like a drugged up ballerina does have its downsides after all.
