grey giant question

I have a grey giant in my account, i have aded the key and done the quest and im vey happy with it.

Now i got another mag from my subscribe and have another grey giant key, as i cant add it to my account i want to know if i can get the quest with my nightfall trial key, have anyone tried this ?

Becouse i think the grey giant key will only work with a retail key.

AFAIK, the gray giant code will only work once on one retail account, and not the trial account.

If I were you, I'd just give it out to somebody as a gesture. It's no good to you....

I'd like to have a Gray Giant, please? I promise not to sell it to anymore. Really. Cross my heart...

If you really want the grey giant, maybe to sell it for the gold, you could just give the key to a good friend let them add it and do the quest then give the pet to you to sell.

Other then that giving it away would be the other option.
