Change Form

Your heritage allows you to naturally transform between your humanoid form and your inherited animal form. Your animal form is determined by your family lineage and is shared by members of your family. This transformation is an innate physical ability, not a magical effect or a spell.

Uses. You can transform a number of times equal to your Proficiency Bonus. You regain all expended uses when you finish a Long Rest.

Transformation. As a Bonus Action, you can transform from your humanoid form into your inherited animal form, or revert to your humanoid form. Each transformation expends one use.

Duration. You can remain in either form indefinitely. Your transformation does not end unless you choose to revert to your other form or another effect explicitly ends this trait.

Creature Type. Your creature type changes from Humanoid to Beast while you are in your animal form and changes back to Humanoid when you revert. This change can affect how spells and other effects interact with you.

If an ongoing spell or effect specifically targets creatures of your previous creature type, changing your creature type can cause you to escape that effect. If the effect requires repeated saving throws, you automatically succeed on the next required saving throw after changing into a form whose creature type is not affected by the spell or effect. This does not remove any conditions or other effects already imposed on you.

Size and Space. Your animal form can be no more than one size category larger or smaller than your humanoid form. You cannot transform if your new form cannot fit within the available space. If a transformation is physically impossible, it fails, you remain in your previous form, and you do not expend a use.

Physical Condition. Your Hit Points and existing conditions and effects remain unchanged when you transform. If you are Incapacitated or unconscious, you cannot transform. If you die, you remain in your current form.

Inherited Form. Your inherited animal form is distinct from transformations caused by other effects. If another effect transforms you into a different creature, that transformation does not replace your inherited animal form. When that effect ends, you return to whichever of your two forms you had before it took effect.

Abilities. You retain your mental abilities and concentration. You cannot normally cast spells or use weapons in your animal form, though the DM may allow exceptions for particularly creative uses or abilities your form can physically perform.

Equipment. Your worn clothing and equipment will NOT transform with you and drop. Exeptions for magical equipment with attunement. 

Flight. You can fly only while in an animal form that has a flying speed. Visible wings in your humanoid form do not grant you a flying speed.

Speech. While in your Beast form, you can understand languages you know, but you cannot speak, as long as your Beast form lacks the vocal anatomy required for speech.

Other Effects. Your transformation is not a spell and cannot be ended by effects that end spells. Other magical effects can still affect you normally, including effects that transform you into another creature.

Escaping Restraints. You can attempt to escape restraints or confined spaces by transforming. Whether you succeed depends on your new form, the available space, and the strength and material of the restraints or enclosure. If the transformation cannot physically succeed, it fails, you remain in your previous form, and you do not expend a use.
