Came across this exploit today on how to dualwield 2-handers. Here is a guide on how to do it.
First make sure to check the auto equip box in option under gameplay.
Secondly wear your main 2-hander.
Then have your bag full except 2 slots.
Give your friend your other 2-hander and another 2 slot item.
Tell your friend to put the random 2 slot item in the first trading box and the 2-hander in the second trading box (but in the same trade session).
Now the first item will go to your bag and the other will autoequip and that being your 2-hander.
Have fun and this will probably be hotfixed very soon, I am also not sure if this will bann you but if it does I am not responsible.
