They seem like a lot of fun.
And what, pray tell, would you be using a rod that vibrates on command for? <wink>Few of them require attunement, but the ones that do are actually fairly useful at lower levels.
I throw a lot of 'minor' magic items into games that are non-combat items. They're the things that a noble would commission to make their lives easier - a pair of shells that can cast message once per day, a rod that vibrates on command, a lens that can count similar objects that the user is viewing, a ring that cleans the wearer as prestidigitation, etc... We use technology a lot - nobles that have access to wizards would likely seek to obtain similar benefits.
Did you mean Moon-Touched Sword?Perfume of Bewitching and Moonblade are the ones that se common use imc.
