Banner of the Fallen Unicorn

This banner shimmers and shines with the scene of a peaceful forest glade. The banner shifts colors from lush greens to deep reds and even gathers snow depending on the changing of the seasons. Blazoned in the center of the banner's background is a red unicorn rampant. Any close inspection of the banner will reveal that the rough outline of the unicorn, thought to be sketched in red paint, is in fact a large bloodstain. The banner is traditionally placed upon a pole and remains furled until use. 

As an action on your turn, you may unfurled the Banner and plant it in the ground; the area around which it is set (30 ft radius) is considered blessed as if it was the domain of an actual unicorn. Once unfurled, the banner cannot be used again until you finish a long rest.

Transformed by the creature’s celestial blood, the area around the banner, 30 ft radius, includes all of the following magical effects:

• Open flames of a nonmagical nature are extinguished within the unicorn’s domain. Torches and campfires refuse to burn, but closed lanterns are unaffected.
• Creatures attuned to the Banner have an easier time hiding; they have advantage on all Dexterity (Stealth) checks made to hide.
• When a good-aligned creature casts a spell or uses a magical effect that causes another good-aligned creature to regain hit points, the target regains the maximum number of hit points possible for the spell or effect.
• Curses affecting any good-aligned creature are suppressed.
