The subject of wands in itself is a rabbit hole that's been made quite inaccessible on internet, mainly by Harry Potter. It's easy to find wands for sale, but information about wands is a bit harder to obtain. A pen could be a wand, but it's more than a wand. You can spell words with a pen. Wands can only cast spells.
I don't know the power of spells. Words can be powerful, I know that.
