Taldaline's Star Shower

A 20-foot-radius cylinder centered at a point you choose within range if filled with falling motes of starry energy. For the spell’s duration, each creature that enters the cylinder for the first time or ends their turn there must succeed on a dexterity saving throw or take 4d6 Fire Damage or half as much on a successful save.

The area within the cylinder is considered bright light and sheds dim light in an additional 40 feet from the cylinder.

Creatures within the cylinder have disadvantage on Wisdom (Perception) checks made to see outside of the cylinder.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 4th.
