Potent Cantrip is a Wizard feature gained at level 3 in the 2024 SRD. Your damaging cantrips affect even creatures that avoid the brunt of the effect.
Your damaging cantrips affect even creatures that avoid the brunt of the effect. When you cast a cantrip at a creature and you miss with the attack roll or the target succeeds on a saving throw against the cantrip, the target takes half the cantrip’s damage (if any) but suffers no additional effect from the cantrip.
