Since we have the worked iron medallion, I think allow a person one permanent custom Master-level forging descriptor upon reaching Legendary smith. When I reached Legendary smith after Ellodin, the text said I was one of the most storied craftsmen in the history of Achaea. With Legendary smith meaning that, it would be logical if such a person had a "signature" descriptor that he or she invented and refined. This would give people great incentive to get to Legendary smith and would add to the game in a way that I think is logical for this type of achievement.
Thank you for reading my idea.
