While you are in direct moonlight (not merely nighttime, and not through heavy cover), the mark flares with pale light.
While the mark is flaring in direct moonlight
You have disadvantage on Dexterity (Stealth) checks
You cannot benefit from being invisible for the purpose of hiding (you may still be invisible for the effects of combat related mechanics, but the glow gives your position away enough to prevent hiding).
you can call on the Fey you met for guidance as below
Pawlight Guidance (1/Long Rest): As a bonus action, you ask the fey for a sign. Choose one:
Silver Tail-Thread You learn the direction (not distance) to one creature, object, or location you can name that is on the same plane of existence, provided it is within 1 mile.
Moon-Mew Warning: The DM answers one question that can be answered with a short answer about the immediate area, this may or may not be correct this is a fey afterall (such as the presence of danger, a hidden door, the safest route, this will not provide any lore hints).
When you use Moon Guidance, the fey becomes unmistakably aware of your situation and may choose to respond in other ways at the DM’s discretion.
Removing the Mark
The mark can be suppressed for 24 hours by covering it with cold iron for 1 minute, or removed only by ending the underlying failure (win one of his games)
