As a Drider your DEX stat increases by +2 and either your STR or CON increase by +1

Driders mature similarly to Elves as they originally were cursed Drow, reaching physical maturity at 18, but often not being considered a full adult until 100 if raised in society, and surprisingly Driders can live up to 750 years old.

Driders typically prioritize self preservation over much else, due to their nature instilling fear and hatred into nearly everything that comes across them. This often leads Driders toward Evil alignments, and an equal chance of leaning into Law or Chaos.

Driders keep the slender upper bodies of Drow, and their lower bodies have the terrifying elegance of Giant Spiders. A Drider typically stands taller than Most races generally around 8 to 9 feet tall. Your size is large for the purpose of how much space you take up, but not for reach or damage.

Driders have a natural walking and climbing speed of 30 feet.

Driders are creatures native to the Underdark and originally Drow, as such they retain the Drow's ability to see and thrive in the dark where others couldn't. You can see in dim light within 120 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.

Creatures born of the Underdark typically have a strong aversion to sunlight. Like their Drow kin, Driders have difficulty seeing when out during daylight hours. You have disadvantage on attack rolls and on Wisdom (Perception) checks that rely on sight when you, the target of your attack, or whatever you are trying to perceive is in direct sunlight.

Driders, due to their Elven origins, don’t need to sleep. Instead, they meditate deeply, remaining semiconscious, for 4 hours a day. (The Common word for such meditation is “trance.”) While meditating, you can dream after a fashion; such dreams are actually mental exercises that have become reflexive through years of practice. After resting in this way, you gain the same benefit that a human does from 8 hours of sleep.

Driders Typically come from the Underdark, and as such are raised largely with the language know there. As a Drider you know Common and Undercommon

 You have advantage on saving throws against being charmed, and magic can’t put you to sleep.

Driders are capable of scaling most surfaces with relative ease. You can climb solid surfaces, including upside down, without needing to make a check and leaving your hands free. You also do not suffer a movement penalty for difficult terrain caused by Webbing.

A Drider's lower half is that of a Giant Spider, as such it comes with a number of benefits and disadvantages. You count as one size larger when determining your carrying capacity, and how much weight you can push, drag and lift. One Medium or Small creature can ride on your back, and you continue to act on your own turn independently of your rider. 

Driders generate silk and webs like spiders do, and as such they have a natural affinity for weaving. You gain proficiency in Weaver's Tools. Additionally, you can spend an hour to work with your silk. Over the course of an hour you can choose to do one of these things:

• You can use your silk to craft a Net. Your DM may ask you to make a skill check to complete this task, and for the purposes of this check you add your proficiency bonus.
• You can choose to spend one hour to coat a space in webs, turning the area into non-magical difficult terrain.
• You can spend one hour to use your webs to make a space for you to rest. this space is considered comfortable for you and persists throughout a Long Rest.

You can use this feature once per Long Rest
