Arachas The Witcher 3 Bestiary

Video shows The Witcher 3 Arachas Wild Hunt monster.
Geralt encounters the Arachas in a forest clearing after meeting Iorveth. This takes place close to the end of Chapter I during the quest "The Assassins of Kings".

The arachas is easily dispatched using a silver sword. It drops some reagents including the arachas eyes and armor. The eyes are used for restoring the power to the amulet in the quest Melitele's Heart.

On Roche's path, a second arachas is encountered at the end of a ravine northeast of the Kaedweni camp, near a lone dead conifer. There is a third arachas in a ravine guarding the Mage's Gloves, this is accessible to both paths.

On Iorveth's path, an arachas is encountered in the cave on the way into Loc Muinne.

By Chapter 2, Geralt's level should be high enough for the Arachas to not give XP when killed.
