@Gadd Fan: I think he was asking whether there was a place they could be used that would allow him to get around the 10 second delay, not the areas that they were (ab)used in. (Though why they added a delay rather than change the creature type is beyond me.)
Afaik, there isn't one. There's the Loose Magic effect in the Divinity Coast explorable but I haven't heard that it'll cancel the timer. With tonics it's possible to use two at a time if you click quickly enough; perhaps this is possible with gitb's too. In any case, running between two areas ought to be faster than waiting out the 10 seconds.
