Story from Within
Changeling Race Homebrew
Changeling (from Eberron website):
The conversion rules are presented “in draft form only”, with Wizards suggesting that they are “usable in your campaign but not fully tempered by playtests and design iterations”.
Changelings are subtle shapeshifters capable of changing their appearance. Their ability to adopt the shape of other hominoids makes them consummate spies and criminals.
As a changeling, you have the following racial traits:
Ability Score Increase: Your Dexterity and Charisma scores increase by 1.
Size: Changelings are built much like humans, but a little leaner. Your size is Medium.
Speed: Your base walking speed is 30 feet.
Languages: You can speak, read, and write Common and two other languages of your choice.
Duplicity: You gain proficiency in the Deception skill.
Shapechanger. As an action, you can polymorph into any humanoid of your size that you have seen, or back into your true form. However, your equipment/clothes do not change with you. If you die, you revert to your natural appearance.
Can change into core races that are “like” humans, within size category (Dwarves, Elves, etc), but not smaller (like Halflings) or larger.
Voice pitch would generically change (ie higher for a female), but would not mimic the target without Study.
Does not and cannot change location of internal organs, though gender parts can change.
Size can only change half again the character’s normal weight.
Advantages: At levels 1-10, anyone who has had interactions with the “changed shape”, even if they don’t really know them, they will gain Advantage on seeing through your “change”
At level 11 and beyond, others have Disadvantage on seeing through your “change.”
Exception: Anyone who is familiar with the person you are disguised as Always has Advantage on seeing through your “disguise.”
Mimic: To try and really take over an identify, traits, and mannerisms of a target, the Changeling will make a performance check / Acting after at least a Week of “Constant, Solid Study” of the target.
