So if I use a stone on an alt, that's it for that account? Even if someone else uses their stone on you, they can't do it for any alt on that account that used one already?
You have to separate using the stones and receiving them. Each Account can only receive one Leveling Stone on a single toon. So, if you account has 6 toons, one of them can benefit from the leveling stone. The other 5 cannot. Who uses the stone on your toon is irrelevant. It could be you, it could be someone else.
You can use as many stones as you have. I have 5 because I got a collectors set. (Well, 15 actually because I bought 3 of them on 3 different accounts). I can use 3 of the 15 on my 3 accounts. One each. The other 12, I have to use on other people's accounts. Presumably, people who did not buy the x-pack. If I use them on my own account, the stone is gone for good. If I use it on another account's toon, I will get a replacement in the mail. Thus, I actually have 18 stones to use (15 + 3 replacements when I use a stone on someone else). If I use 3 of my stones on other people, I will get a free new companion in the mail.
That's my understanding of how it works.
