if you have a friend who is still on cooldown from the token shop and wants another item that they think might go out of stock before they can get it, and you have already gotten what you wanted, could you buy something for them? or would that be abusing the system? thanks in advance!
As far as I know, isn't that just getting you a gift? And that's not against the rules. As long as you're each only playing on your own account, and not using one account to funnel items to the other.
The main rule regarding this situation is that you don't use the Shoutbox to arrange it.
No Advertising in the Shoutbox
Other than that, they're your wizard tokens and your chance to purchase from the Token Shop, you can do what you like with them. Just be aware that there is a cooldown period for the Token Shop, and don't violate any other site rules as others have mentioned.
If you ever have other questions about the rules and if something's allowed or not, it's better to fill out a ticket to ask staff directly for an official answer!
