While a drider is often created while an adult, if not they mature at the same rate as humans and can live to be 750 years old.

Tend to be as evil or neutral, the teachings of drow made them wicked but often their transformations give them some form of humility.

Your base walking speed is 30 feet and you have a base climbing speed of 20 feet.

You can climb normally for any surfaces or objects that have obvious features, such as cave walls, trees, statues, and some buildings. For featureless surfaces, as long as they are not perfectly smooth or slick (like glass or polished stone) you may climb them as if it were difficult terrain. You may stay on a surface between turns. If you are attacked while clinging to a surface, you must make a Constitution save to stay attached--DC 10 for normal surfaces, and DC 15 for featureless surfaces. A failure means you fall prone and take fall damage.

You are not built for swimming and have a swim speed of 0.

While in sunlight, the drow has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.

Accustomed to nocturnal activity, caves and dark dwellings, driders have superior vision in dark and dim conditions. Arachne can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.

While there are surely advantages to being a hybrid, there are a number of ways in which the monstrous half is a detriment.

• due to your lower body, you cannot make use of mounts.
• You have two creature types: humanoid and monstrosity. You can be affected by a game effect if it works on either of your creature types.
• As you lack the lower body of a humanoid, you are unable to wear humanoid armor below the belt (ex: leggings, greaves, or boots).
• Many people fear you or may regard you with hostility. Other creatures naturally distrust you, and you have disadvantage on persuasion and diplomacy checks for creatures that you are not familiar with. Others may permanently regard you as an abomination.
• You are not built for swimming and have a swim speed of 0.
• your armour requires somewhere in between two to three times the materials to be made. It is about that much more expensive, and that's assuming you can find it. Based on how common these races are in your world, they might be found in populous cities or specifially a Drow city. You don't require larger shields.

You can speak, read, and write Common and Undercommon.

you ignores movement restrictions caused by webbing.
While in contact with a web, the arachne knows the exact location of any other creature in contact with the same web.
