Quick question about wands. My alchemist recently acquired a wand of false life which also happens to be a level 2 extract in the alchemist formula book; does he have to use the use magic device skill to activate the wand? Or is that unnecessary because it's part of his formula book?
If it's on your class formula list you can use it without a problem. It's only for spell completion items (such as scrolls), that you would need UMD for.
