Command

You speak a one-word command to a creature
you can see within range. The target must
succeed on a Wisdom saving throw or follow the
command on its next turn. The spell has no
effect if the target is undead, if it doesn't
understand your language, or if your command is directly harmful to it.
When you cast this spell using a spell slot of 2nd
level or higher, you can affect one additional
creature for each slot level above 1st.
