You as an Arc-Chained have received certain augmentations from your creator to assist in your work

Your arcane eye implant gives you dark vision in that eye up to 30ft.

You get one limb that is replaced with an arcane implement. This allows you to choose one of the three available traits:

1) Limb Augmentation. You gain proficiency in either Acrobatics or Athletics. At 5th Level you gain a +1 bonus to your Dexterity score if you chose Acrobatics or Strength if you chose Athletics.

2) Magical Shielding. You can make a Con saving throw instead of a Cha,Wis or Int saving throw against spell effects. You are considered proficient for Con. saving throws for this one if you aren't already. You can do this one time per Short Rest.

3) Gain thermal shielding against either Fire or Cold(Your choice). You are immune to weather effects from the matching weather(Immune to exhaustion from either heat or cold). You are also able to use a reaction to half the damage from your matching damage type(One time per Long Rest)

As a creature that relies on the powers of the arcane to keep themselves running, you are extremely vulnerable to dispel magic, however, you are not defenseless. With the aid of another source of magical energy, you can recharge your augments into running condition or simply take a rest to allow it to recharge off your own body's energy.

You have a +2 to Constitution and a +1 to another Stat of your choice

Mature at the same rate as humans but usually don't receive their more extensive augmentations until they reach adulthood and have a shortened live span as a result of the stress of the augments on the body. Live span from 50-70 years

Their allegiances to either chaos and law are as flexible as any human but they rarely align to either good or evil

Humans vary widely in height and build, from barely 5 feet to well over 6 feet tall. Regardless of your position in that range, your size is Medium.

Your base walking speed is 30 feet.

You can speak, read, and write Common and one extra language of your choice. Humans typically learn the languages of other peoples they deal with, including obscure dialects. They are fond of sprinkling their speech with words borrowed from other tongues: Orc curses, Elvish musical expressions, Dwarvish military phrases, and so on.
