Because you are a fiend, you have superior vision in dark and dim conditions. 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.

Your creature type is considered to be Fiend, and you are considered to have the Shapechanger tag. Additionally, you are vulnerable to radiant damage.

Your Charisma and Dexterity score increased by 1.

Flamelings mature slightly faster than humans but share a similar lifespan—typically a century or less. While a flameling can transform to conceal their age, the effects of aging affect them similarly to humans.

Due to their fiendish natures, flamelings often tend toward evil alignments. Neutral or good flamelings are extremely rare, but not unheard of. They have no particularly tendency toward or against lawful or chaotic alignments.

Your size is Medium. To set your height and weight randomly, start with rolling a size modifier:

Size modifier = 2d4

Height = 5 feet + 1 inch + your size modifier in inches

Weight in pounds = 115 + (2d4 × your size modifier)

Your base walking speed is 30 feet.

As an action, you can change your appearance and your voice. You determine the specifics of the changes, including your coloration, hair length, and sex. You can also adjust your height and weight, but not so much that your size changes. You can make yourself appear as a member of another race, though none of your game statistics change. You can’t duplicate the appearance of a creature you’ve never seen, and you must adopt a form that has the same basic arrangement of limbs that you have. Your clothing and equipment aren’t changed by this trait.

You stay in the new form until you use an action to revert to your true form or until you die.

You have proficiency with the Persuasion skill.

You have a small pair of wings that give you a flying speed equal to your walking speed. However, these wings are not strong enough to hold you weight for an extended period of time. You fall if you end your turn in midair, you started in midair, and nothing else is holding you aloft.
