Arachnos are basically purple, green, or rusty orange colored monsters that are half spider and half man. They are found in several places around Greece (Act I) and usually attack in medium-sized groups. They are divided into three classes: Drones, Runeweavers, and Elites. Drones are basic soldiers armed with a light weapon and some armour. Runeweavers are generally tougher, and attack with a ranged poison attack. Elite soldiers are a buffed version of the drone, with a higher attack, more health, and generally better weapons and armor. Although not difficult individually, their pack-nature can make them dangerous, especially when supported by runeweavers.
They get to use various special armor pieces like the Arachnos Chitin. They can also drop the rare Deathweaver's Legtip, a dagger/sword with poison damage.
Tropical Arachnos are an Arachnos sub-species.
