Arachnomorph

The arachnomorph is essentially a large spider akin to the giant spiders from lord of the rings, this post conjunction creature prefers deep damp caves and the occasional, isolated swamp. They are a relatively new creature in the witcher universe, appearing for the first time in the Witcher 3 expansion pack Heart of Stone. According to the bio, those who venture into an arachnomorphs lair had better have a clear conscience and checked everything off his/her bucket list. For these large spiders don't shy away from human meat, they're considered so dangerous that few witchers are capable of killing them. There is an even larger arachnomorph known as collossi, capable of eating a whole ox within seconds.

When fighting these creatures the rule of thumb is to stay mobile, while this applies to fighting all monsters the spiders have the ability to spit webbing that can stop the player in his/her tracks; leaving him/her vulnerable to further attack. The spiders attack as one when the odds are in their favor, but when the player starts to attack they retreat leaving the player frustratingly out of reach. Yrden is especially useful, for it slows and hurts arachnomorphs, igni too can set the creatures alight and buy yourself some time to combat the rest.

The bio for these spiders says they like caves, yet while venturing outside they can be encountered in forests similar to packs of wolves, waiting for dinner.
