Players found a way to enter the Valdrakken bank on live servers.
Reddit user lightterrr posted a screenshot to r/wow from inside the Valdrakken bank, casually chilling on a pile of gold with their goblin.
Apparently, only a few classes can get inside. Rogues can Shadowstep the big Dragon banker to get inside the bank. Certain piles of gold will even give you a breath timer. Evoker’s Rescue should also work to get inside when you have a line of sight to the target destination.
However, we do not recommend you try this, as one pile contains a hole in world, which will eventually cause your character to become stuck in an endless loop of disconnects.
