We will monitor Black Market AH for Invincible on 20+ different realms. Once the item appears, we'll transfer your character to the target realm and start bidding using our large stock of gold, we've got a win rate of about 95%. Once the item is obtained, it will be immediately added to your Battle.Net-wide transmog collection. If for some reason we lose the auction, the cost of transfer is refunded to your Battle.Net balance.
