I am unsure if this is even possible to recover, but I was doing Thunderwing and I got an Adrenaline book drop. Considering it’s worth a decent amount of gold I was going to link it in chat for my friends to subtle flex my luck. My hotkey must’ve gotten stuck or non-functioning and only my right click registered withdrawing the book completely accidentally. Is there a way to remove the legendary adrenaline engraving and recover the book? I was planning on selling it or giving it to a friend who does need it as I don’t use adrenaline. Thank you in advance if this can be resolved <3
Hello @bashabasha, 
Welcome to Lost Ark Forums! 
Thank you for sharing your concern related to your accidentally registered book.
I’m sorry to say but once the book is registered, it cannot be recovered back.
We apologize for the trouble you are going through.
There is no means to honor your request regarding the reversal of your book registration. I would suggest you to be extra careful in future while handling the books.
See you in Arkesia!
