As an action, you hurl a 10-centimeters-diameter sphere of energy at a creature that you can touch or see within 9 meters. The creature must make a Reflex saving throw.
On a failed save, the creature takes 1d8 damage.
On a successful save, the creature takes half as much damage.
The number it rolled determines the attack’s damage type.
This spell’s damage increases by 1d8 when you reach 5th level (2d8), 9th level (3d8), 13th level (4d8), and 17th level (5d8), but only the original 1d8 is used to determine the damage type.
