Under the Skin

You are in fact a construct, hiding as another creature type. Gain the Construct creature type and the capabilities of the Warforged "Constructed Resilience." However, you do not gain the other capabilities of warforged.

• You have advantage against saving throws regarding being poisoned, and you have resistance against poison damage.
• You don't need to eat, drink, or breathe.
• You are immune to disease.
• You don't need to sleep, and magic can't put you to sleep.

In order to take this feat, you must have an in-story reason, as well as not already having the Construct creature type.
