1 hour/mana

As an action, a veil of shadows and silence covers you, masking you from detection. For the duration, you have advantage on Stealth checks and can’t be tracked except by magical means. A creature that receives this bonus leaves behind no tracks or other traces of its passage.

Augment

You can expend 1 additional mana so each creature you choose within 5 meters of you (including you) has advantage on Stealth checks and can’t be tracked except by magical means.
