I'm designing a Tiefling Magus that will be using the wand wielded magus arcana. I plan to have a prehensile tail either way both for fun, and to quickly retrieve more wands. The question I have is whether or not a wand can be activated while being held by a tail. A tail can be used to retrieve objects and also hold onto them. A wand uses the spell trigger activation method which doesn't require any fine manipulation. It only requires the item(wand in this case) to be held, and a command word to be spoken. The one serious issue I can see is the statement that it must be held in a hand(or whatever passes for a hand with non-humanoid creatures.) What this boils down to is whether or not a tail passes for one of those. I believe it should but I am biased. Just curious what both the official and non-official have to say.
Thanks
