Arachs come in swarms of up to 20. When they attack each individual will first fire a strand of extremely sticky silk, the intended overall effect being to trap the victim. Once this is done the arachs will surge forward from their hiding places and drop down on their victim from above, biting and stabbing until they are too wae to be capable of defending themselves. Then the arachs will begin feeding regardless of whether their prey is dead yet. They could be described as vampiric as they feed on blood, being incapable of digesting solid food. Once helpless, the victim is quickly drained dry.
