* You can glide a short distance.
* Jumping length is doubled if you are free to use your wings.
* On the other hand, flexible upper-body clothing which doesn't restrict your movement and doesn't cause discomfort needs to be personally fitted, so it costs double; hard armour costs triple. Or you can use a downtime activity paired with the right proficiencies and tools to do it yourself, for slightly cheaper.
* Optional rule: You can jury-rig anything quickly even without the right proficiencies or tools, but the resulting clothing will lose value and suffer wardrobe malfunction in social circumstances whenever the check die shows a natural 1 or 2.
* Additional attack at -5, but can get injured if attacking armed and armoured opponents.
* See above for clothing, but for lower-body.
* Optionally: Birth-giving hips give you an advantage on giving birth.
* Optionally: ... by laying eggs.
* Whenever you cast magic which fits the aspects of the parent's dragon species (typically "fire"), you can make a WIS check plus your proficiency bonus against a DC of 15. No advantages or disadvantages ever apply to this check. If you succeed, you can pick one of the following options:
1. One of the effects (damage, range, duration, ...) is doubled.
2. You don't expand the spell slot if you otherwise would.
3. You cast the effect as if it was a spell level higher.
* Optionally, the DM can lower the DC a bit if you're in an area which is spiritually connected to your parent's dragon species, like a kobold tribe's place of worship.
