Yes you could..... But I somehow can't imagine from what you could create a magic wand...
Maybe: Branch, a hair of unicorn, vein of dragon's hearth maybe?
Oh, sorry, I misunderstood you, I thought you're asking what are planks for, but you were still talking about that damn wand
In this case I agree, plank is a bit large to make a wand out of it...
But please, don't talk about how to create that stupid wand, I won't make it creatable, it would destroy actual game...
