I did a search of this and nothing came up about this so I apologise if this has already been posted
I was searching for a way into old Ironforge and I saw a video where if you polymorph someone near the door
that you could walk right through but after a few failed attempts i had someone tell me a really easy way of doing it
1) First you will need to have a mage with you and both be in Ironforge ready
2) Next thing you do is you stand behind the column just out the front of the Bank (34, 64)
3) When you are both standing in this spot you will be able to challenge each other to a duel
4) Once the duel has started both of you have to run to (47, 60) where there is a window,
stand in the far back corner of it, right up against the wall.
5) Have the mage polymorph you and you will go straight through the wall and into old iron forge.
Please Note: that after you get out of a certain range of the duel flag the timer will start and if you don’t have a
mount it would help to have a swiftness potion on hand ready.
Also make sure you have a hearth stone because there is no way of getting out if you don’t.
