Dopplegangers reach maturity at age 5. Their maximum age is unknown.

Dopplegangers vary widely in alignment, this is due to their flexibility in social settings, and quick learning.

Dopplegangers stand between 5 and 6 feet tall and average about 200 pounds. Your size is Medium.

Your base walking speed is 40 ft.

You 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.

If you surprise a creature and hit it with an attack on your first turn in combat, the attack deals an extra 2d6 damage to it. You can use this trait only once per combat.

Each morning you may change your appearance to replicate the appearance, sound, and size of a small or medium humanoid you have seen throughout your past. This may be an NPC or player introduced in-game within the past week, the DM may also have you make a history check to recall an NPC further from your past that may not be involved in the current immediate setting. Abilities like keen mind may make it so that a history check would no longer be necessary at DM discression.

You may only take on this Alternate Shape. You may revert to your true form at any time throughout the day as a bonus action. You may not take on a new Alternate Shape until the next morning.

When you become incapacitated your alternate shape fades immediately revealing your true form. Abilities like dispell magic and circle of truth also make you revert to your true form. Sleeping does not revert you to your true form.

Anyone wishing to investigate your Alternate Shape must succeed on an investigation check with a DC equivalent to 10 + your deception modifier to know that you are not the humanoid that you are replicating.

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.

You can speak, read, and write Common and one extra language of your choice. Dopplegangers typically learn the languages of other peoples they live near, including obscure dialects.
