What ability set would be bad IRL?

[King of Nowhere]

Are you suggesting that this would be *worse* than owning a knife, or a gun, to know that you could chant some magic words to get a similar effect?

I am a teacher, and i had some really bad kids sometimes. I really would NOT want to be able to cast magic missile at them, just like i would not want to bring a gun. In the heat of a moment i may do something i may regret
