Your practice in shapechanging has granted you a wider field of transformation

• Your Charisma is increased by 1, to a maximum of 20
• When using your Shapechanger racial feature, you may now change your size up to two sizes taller or shorter. Additionally, you may give yourself racial features that are nonhuman, such as a Tiefling's horns and eyes, a Lizardfolk's scales and tail, or an Aarakocra's wings. Any racial feature that grants you movement(i.e. Aarakocra's wings) move as if encumbered by difficult terrain; additionally, Armor Class modifying racial feature(i.e. Lizardfolk scales) do not alter your armor class. This feature does not allow you to change your shape into metal, such as a Warforged. While transformed, you do not gain any ability score increases that are given to other races, nor do you gain any ability score alterations from changing your size category up or down.
