So before we had made our way out to the tower Jørmund would have imbued someone's armor or weapon with the blessing of the forge. Only get to do one person per long rest. Whoever gets it get a +1 to the non magical item. He will likely give it to someone else as he has pretty high AC and will likely use magic more than his mace. He will favor people he has been traveling with longer as well. 

EDIT:  I will say he has been with at least one or two of the other party members for awhile, maybe Flicker or Aura and someone else. What do yall think?
