I'm not sure if I understand how this cantrip works. I really want to use it for silly things, like having my fun-sized -1 strength rogue smack a table indignantly, sending sparks flying everywhere and leaving a black mark on the wood, or sneaking up to a guard and soiling their pants, but that doesn't really work, does it? My DM said that spellcasting breaks stealth, and that typically people can tell that I am casting something if I am casting something, so what would I even use this for, if I basically can't use it to actually trick people? It wouldn't even be possible to cheat at card games, since anyone could tell that I just did some magic. Am I missing something here?
