Physical Capabilities
Daedrian Physiology: Possessing natural armor capable of resisting the strength of most human weapons including normal sized bows, swords, and daggers daedri have a relatively durable chitinous hide. Additionally their joints, including those in their carapace, are lubricated by a natural oily substance, making their movements silent unless they touch something that would make noise. As a result, daedri are considered fairly resilient though they are known to be weak to blunt force trauma, enchanted weaponry, Aehkaerian copper, and any piercing weapon with significant force behind it. In terms of speed, strength, and maneuverability well daedri are relatively impressive in the first and the third being quite capable of climbing even on stony surfaces, though they prefer to make wooded areas and caves their homes. In terms of strength, daedri are quite capable of tearing through flesh, breaking human bones, or tearing entire limbs off should they have the proper grip. However, due to the sheer length of their fingers and their hard chitinous nature, daedri are not well known for using weapons--though this is not to say that they cannot, just don't expect to see a daedri wielding a sword or a mace.
Daedri eye colors range between yellows and reds with several layers of black 'film,' which act both like lenses and eyelids, protecting the eyes and allowing them to shift their vision between detecting mana and detecting visible light. Despite this, daedri have relatively poor eyesight as they can only see about 3 meters from themselves, though they have other senses to make up for it. In particular their sense of smell is fairly sharp, allowing them to detect pheromones from one another as well as differentiate species purely by smell--though individuals are harder. On the bottom of their oval shaped head are a series of ridges that act much like those on a snake, giving them a sort of thermal sense that extends past their field of view. Last, in regards to their senses, daedri have an almost 360 degree field of view due to the position of their eyes--though their terrible eyesight does weaken this advantage somewhat. Luckily, like spiders, daedri are sensitive to vibrations. Oh yeah, and daedri are sentient, cunning bastards, deal with it.
Note: Daedri are omnivores, but prefer meat.Note: Daedri are incapable of human speech due to their differences in their vocal cords and mouth structure.Acidic Venom: Due to the tough prey that daedri tend to hunt, as well as the creatures larger than themselves, the arachnoids have developed an acid that is created in glands within their mouth. these glands are attached to two parts of their mouth, one being a pseudo tongue with a long tube/hole in it, which allows them to 'spit' the acid forwards up to twenty(20) or so feet. The second part that these glands are connected to are their fangs, thus allowing them to inject the terribly corrosive substance directly into their prey typically resulting in a very painful death. In short, don't get bitten.
Note: Due to their injecting acid into their prey prior to eating it, daedri blood is acidic, though it is less acidic than their undiluted venom.Magical Capabilities
Mana Infusion: A mostly passive magic which all healthy daedri possess, these creatures infuse mana into their silk allowing them to track it as well as to increase its durability. Some daedri can expand their magical capabilities further than this, allowing them the use of true magic, but for most this is all they know or will ever be capable of. It should be noted that their mana 'sticks' to things even if their web does not.
