'You have progressed a great deal, (your name), but if you do not study the efforts of your betters, you can never hope to exceed them.
'You should speak with Glasi Ironhand, a skilled metalsmith in the Blue Mountains. Look for him at the forges of Thorin's Hall.
'Do not be discouraged if he feels you are unready! The Ironhand is very particular about whom he chooses to train and is very likely to turn you away.'
Your skill as a metalsmith has improved, but you still have much to learn.
Talk to Glasi Ironhand
You may find Glasi wondering around The Forging Hall in the NE corner of Thorin's hall.
