Shapechanger Heritage

Changeling (self or ancestor)

If you touch a dead or incapacitated humanoid for 1 minute, you gain the ability to cast the Disguise Self spell and take on that creature's appearance for the next 24 hours. Once you have adopted a creature's appearance this way, you cannot do so again until you complete a long rest.   If another creature attempts to discern your appearance is illusionary, they must make an Intelligence (Investigation) check with a spell save DC equal to 10 + your proficiency bonus.
