When a cantrip spell is cast the player rolls 1D6 and applies the results listed below. This is to add some variety to Pew-Pew-Itis when casting the same cantrips over and over again...
This was inspired by Sergey Pomerantsev over on MeWe.
1. Critical Failure. No damage or effect. Fumble.
2. Less range or damage or reduced effect.
5. Increased range or damage or increased effect.
6. Critical success. Max damage or effect.
