You can now take the Dash action on a bonus action while hidden, in dim-light, or in darkness.

You can see in dim light within 120 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.

You are more undead than anticipated. You are immune to the effects of the first 2 levels of exhaustion,  as well as disease and hunger based effects.
