Master Changeling

Prerequisite: Changeling level 5

After extensive training, you've gained a larger amount of control over your shifting body, even allowing you to manifest traits from other humanoids when you change forms. You gain the following benefits:

Ability Score Improvement. Increase your Dexterity, Constitution, or Charisma by 1, to a maximum of 20.

Quick Shapechange. You gain the ability to use Shapechanger on your turn as a bonus action, rather than as an action.

Mimicked Feature. When you use your Shapechanger racial trait, you can choose to manifest one of the following body parts as a part of your appearance change, granting certain benefits when you do:

•  Elven Eyes. You gain darkvision out to a range of 60 feet. In that radius, you can see in dim light as if it were bright light and in darkness as if it were dim light.
•  Tabaxian Claws. You gain a climb speed equal to half your walking speed. Additionally, your claws are natural weapons you can use to make unarmed strikes. When you hit with them, the strike deals 1d4 + your Strength modifier slashing damage, instead of the bludgeoning damage normal for an unarmed strike.
• Goliath Frame. You count as one size larger when determing your carrying capacity and the weight you can push, drag, or lift.
•  Triton Lungs. You gain a swimming speed equal to half your walking speed, and can breathe air and water.

These benefits last until you use this feature again, revert to your true form, or die.
