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.
