Lord/Lady needs a tutor quest is nearly impossible since we can't access quest companions' inventories anymore

Since we can no longer access quest companions' inventories to change their loadouts and since many of these heroes have maxed combat skills, it makes doing this quest extremely difficult. It used to be easy enough to train them in bow, crossbow, throwing, etc. but since they now always will use the same weapons that's not an option.

I heard the best way to upgrade is to use him for the smithy. He seems not to upgrade at all from battles and missions

Maybe, but sitting there grinding out 60 smithing for an NPC while the Khuzait conquer the world isn't much of an option.

This is how I completed the quest. They have 0 in smithing, so it was quite easy to level.
