If you have unintentionally redeemed Gold or Spirit in-game for an incorrect item, we are unable to reverse those item redemptions. As such, we do recommend being very careful with future item redemptions of this nature.
If you have unintentionally redeemed Diamonds for an incorrect Spirit Orb, and have not opened the Spirit Orbs please create a support ticket. We are able to exchange orbs in this situation.
Please note: If you open a Spirit Orb, even if you redeemed Diamonds for it, we will not be able to exchange the orb for you.
