Red Chromatic Rose

While holding the rose by its stem, you gain resistance to fire damage. If you would take more than 10 fire damage from a single source (after applying the resistance), the rose disintegrates and
you take no damage instead. As an action, you can blow the petals from the rose to produce a 20 ft.
cone of fire. Each creature in the cone must make a
DC 15 Constitution saving throw, taking 3d10 fire damage on a failed save, or half as much damage on
a successful one. Using this property destroys the rose.
