You transform into a spectral wolf, gaining increased mobility and resilience. While in this form:   Your movement speed increases to 60 feet.   You have advantage on Dexterity (Stealth) checks made in natural environments.   You can move through difficult terrain without penalty.   You can revert to your normal form as a bonus action. The transformation ends early if you are reduced to 0 hit points or if you choose to dismiss it (no action required).
