Abuse but not harm

So this spell's balance is a little out of wack. First most cantrips do not get a spell save dc and the spell save dc would be the caster's dc. Second this spell is already in the game basically as hold person, (a 2nd level spell) and it paralyzes for one minute, or 10 rounds of combat unless A. the caster loses concentration, or B. the target succeeds the DC. For a cantrip to on one side have a spell save dc of 10 which is really weak, and then on the other side if the target fails the save they automatically lose 2 rounds of combat, plus they are then paralyzed for 10 minutes just makes this spell very badly balanced.

Paralyzed already prevents using actions and reactions

Imagine saying "I cast Abuse but not harm" out loud at a table in a gaming shop. Imagine all the uninvolved faces that turn towards you, confused and horrified by what you have just said. They will never play Dungeons and Dragons. They fear the spell.

I casted this once and they took me out behind the store and shot me in the back of the head.
