You are a Construct.

You are Medium.

Your walking speed is 30 feet.

You are encased in thin metal or some other durable material. While you aren’t wearing armor, your base Armor Class is 13 + your Dexterity modifier.

You know the mage hand cantrip, and the hand is invisible when you cast the cantrip with this trait.

Starting at 3rd level, you can cast the shield spell with this trait. Starting at 5th level, you can also cast the detect thoughts spell with it. Once you cast shield or detect thoughts with this trait, you can’t cast that spell with it again until you finish a long rest. You can also cast either of those spells using any spell slots you have of the appropriate level.

Intelligence, Wisdom, or Charisma is your spellcasting ability for these spells when you cast them with this trait (choose when you select this race). None of these spells require spell components when you cast them with this trait.
Also you gain a resistance to psychic damage as is normal for Gith.

If the mending spell is cast on you, you can spend a Hit Die, roll it, and regain a number of hit points equal to the roll plus your Constitution modifier (minimum of 1 hit point).

In addition, your creator designed you to benefit from several spells that preserve life but that normally don’t affect Constructs: cure wounds, healing word, mass cure wounds, mass healing word, and spare the dying.

You have resistance to poison damage and immunity to disease, and you have advantage on saving throws against being paralyzed or poisoned. You don’t need to eat, drink, or breathe.

When you take a long rest, you spend at least 6 hours in an inactive, motionless state, instead of sleeping. In this state, you appear inert, but you remain conscious.

You gain two tool proficiencies of your choice, selected from the Player’s Handbook.
