Cantrip Expert

You've learned to master the basics of the arcane.

 Once per turn when you roll the damage for a cantrip you can roll one additional die and add it to the total damage. The die is the same as the die of the cantrip.

 When a creature succeeds on a saving throw against your cantrip, the creature takes half the cantrip's damage (if any) but suffers no additional effect from the cantrip.
