You conjure a huge spectral sunflower which rises from the ground at a point that you can see within range and lasts for the duration. The flower sheds bright light in a 20-foot radius and dim light for an additional 20 feet, which is sunlight. The flower is incorporeal and does not occupy space. You can use a bonus action on each of your turns before the spell ends to cause the flower to release blazing sunlight in a blast. Choose one of the following two options each time you do so.

Area Blast. Choose either a 15-foot-radius, 100-foot-high cylinder centered on the flower, a 40-foot cone blasting from the flower, or a line 80 feet long and 5 feet wide blasting from the flower. Each creature in the chosen area must make a Constitution saving throw, taking 6d6 radiant damage on a failed save, or half as much damage on a success. Undead and oozes have disadvantage on this roll.

Single Target. Make a ranged spell attack against a target within 150 feet of the flower that you can see. Determine cover and line of effect for this attack as if it was made from the flower's location rather than your location. On a hit, the target takes 8d6 radiant damage. You have advantage on this attack roll against undead and oozes.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage dealt increases by 1d6 for each slot level above 5th.
