Hmm, the words are interesting but I always found it more impressive if a character just stood there and summoned big spells without saying anything or moving. Part of what I hate about Harry Potter, I suppose. I just can't stand those silly wands and movements.
But if you give all your spells names, that does add some flavor to it. Not to mention that you can always get reactions along the lines of:,, Eh, what did she just say? Wait a minute...OMG, NOT THAT SPELL!!! AAAHH!!!"
