First of all, I have no idea if this is called "Going through walls" or if it's in the right section. I just discovered this, because I was bored waiting for a friend to join me in ZG.
Also, I couldn't find anything using this way with the search button.
I do know, that it's easily possible to go through walls like this, but couldn't find any posts with the burgy blackheart's handsome hat. only pots that make you grow bigger etc .
Requirements:
*Burgy Blackheart's Handsome Hat
*A mammoth mount or any other mount that grows a bunch when you use the hat.
I were at this spot: https://i.imgur.com/2fGpsmW.jpg
So what I did was, mount up and then simply take on the Hat. Then I was able to go through the wall.
