You can take the Magic action to transform into an humanoid creature with an equivalent appearance, or back to your normal form. While transformed through this feature, you ignore the effects of your Undeathly Gaze feature, and creatures detect, perceive, or sense you as a humanoid creature.
Any effect that would cause a humanoid creature to regain hit points or remove a condition can also affect you.
You can add your training die to any ability check you make with an untrained skill or tool.
