What is the process for turning a yumi into a one handed yumi?
I read many posts on here that you have to use a related deed but can't find any posts talking about how this process is done. I have relayed weapons into armor so I understand that process.
Would someone please reply with a step by step, thank you.

When you use a relayer deed on a weapon, the first menu gives you an option of turning the weapon into a 'wearable relayer', or 'change to one handed'. I believe the option for one handed is only given on two handed weapons, as well.
