I have two ideas for improving the friend request system:
1) Have a message sent to the original wizard "Wizard2 has declined your request" or similar. As it is, the game shows nothing, and the first wizard doesn't know if the request has been declined, seen, or even sent.
2) Have a timer so that the original wizard can't repeat the request again for a certain length of time (1-3 minutes seems reasonable). The message might be "You just requested friendship with this wizard." If the second wizard accidentally declined, he/she can fix it by making the request himself/herself. The timer will prevent wizards from spamming friendship requests.
