Monks of the Way of the Metamorph wield ki to transcend the limits of flesh, reshaping their bodies into fluid instruments of adaptation. Muscles swell or shrink, skin hardens or flows, limbs elongate into claws or blades—all in an instant. They infiltrate as silent spies, strike as predatory beasts, and persuade as trusted allies, their form ever-changing to dominate any battlefield or social intrigue. To a Metamorph, perfection lies not in rigid control, but in boundless transformation.

Adept Shapechanger

3rd-level Way of the Metamorph feature

As an action or bonus action, you can change your appearance and your voice. You determine the specifics of the changes, including your coloration, hair length, scent, and sex. You can also adjust your height and weight and can change your size between your normal size and one size smaller than your normal size. 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 an individual 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 but you can mimic the appearance of a worn outfit, these garments are living tissue: they move like the outfit, feel like outfit, but they are part of you and cannot be removed. The mimicked outfit must plausibly fit beneath or replace whatever you currently wear if your are wearing anything. For example beneath full plate you can only imitate garments that could be hidden under armor; you cannot sprout a second suit of plate from your own flesh. Your statistics are not changed by the mimicked outfit.

Creatures with Truesight cannot see through this disguise or when you become invisible using your Empty Body feature.

You stay in the new form until you choose to revert to your true form (no action required).

Using your ability to shapechange you can manifest natural weapons such as spikes, horns, sharpened teeth, or fangs to deal piercing damage, claws, or blades that deal slashing damage, or a tail or hardened limbs that deal bludgeoning damage. When you use your unarmed strike you can change the damage type to either piercing or slashing damage and the reach of your unarmed strikes can increase to 10 feet.
