If I delete my Shadowforge Key, can i get it back somehow?

I haven’t delated it. Just curious. I see that other items like the necklace to enter Onyxia’s Lair can be retrieved by speaking with an NPC. What about this key.?

Worst case if there isn’t Blizz will restore it if they see you completed the quest

I wouldn’t rely on this.

Better make an effort to the bank and put it there.

There is an item restore page under your blizzard account on the website. I’d link the page but I’m at work and can’t access it. I’d check there and see if there is an option to restore it.

Edit: Just reread your post and saw you were just curious but if that did happen that would be my 1st step.
