Scream is a noun. Fails to work.
Salute is a noun. Fails to work.
Not a verb.
Not a verb. And, even if it was, casting a spell in front of the lord and then forcing someone to spit is probably not going to work.
"Yes, it's true. My name is Hussar."
"I cannot tell a lie. I did fart a few minutes ago.
So, we're allowing 1st level spells to recreate the effect of 3rd level spells now? Moonbeam? Wow, that's a hell of a spell.
Yeah, because mind controlling someone to commit a crime isn't going to be a problem. And, "The NPC puts a hand in front of their face" They're defaced. Since you cannot force somone to act on another object using this spell it doesn't work.
Umm, because all the basic descriptions of the standard Commands are combat effects?
But, yeah, all these "creative" uses either rely on the DM ignoring the actual rules of the spell (forcing the NPC to take an action using an object they they are not holding) or ignore the rules of the English languages. You want to a mind control spell? Take Domination. You want a short term duration action denial and battlefield control spell? Take Command.
