Auril's Brand (Immune)

This brand is given as a boon to those who are loyal to Auril, or to those she wishes to entice into her fold. It serves as a marker, as well, to signal that the gifted individual is owned by the Cold Goddess. The tattoo is a six-pointed snowflake, with fractal branches poking out along the stem of each point, and it is administered like a brand normally would be. However, the branding itself will not be felt with heat, but instead with a biting cold, as the freezing magic eats away at the skin, forming the pattern of Auril's brand.
After the deed is done, the brand appears as a tattoo rather than a branding scar, and offers a small gift to the bearer.

Those who bear this brand gain a resistance to cold damage, or immunity if they are already resistant, and allows them to raise a bed of Auril's Flowers once per long rest.

Auril's Flowers
Stalagmite, and much smaller, sized shards of ice erupt from the ground up from a point you can see within a range of 60 feet. Each creature within a 10 foot radius centered on that point must make a Dexterity saving throw. If failed, the creature takes 4d8 cold damage and is knocked prone. If the creature succeeds on the saving throw, they take half the damage and remain upright. If a creature is killed by this bed of flowers, their body is turned to ice and the damage roll for the next use gets one extra dice.
