Chief Blacksmith

Chief Blacksmith (鍛冶長) is an NPC created by Amanomahitotsu.

Background
During his time in YGGDRASIL, one of the Supreme Beings, Amanomahitotsu, created the Chief Blacksmith who was designed as his apprentice and assigned to do blacksmith work.

The Bloody Valkyrie Arc
Under the identity of Momon, Ainz Ooal Gown had successfully gained the approval of Pluton Ainzach to engage the vampire plaguing the vicinity of E-Rantel. He made preparations to create evidence of a battle, ordering the Chief Blacksmith to create a duplicate set of his armor with realistic battle damage.

The Two Leaders Arc
It was mentioned by Aura Bella Fiora that the blacksmith was in the process of making a suit of armor for Hamsuke.

Ainz Raises Money Arc
After receiving gold coins from Ainz Ooal Gown as part of their salary, Shalltear Bloodfallen had the Chief Blacksmith, craft two of the gold coins into a brasserie for her to wear.

Mass for the Dead Arc
The Chief Blacksmith assisted the protagonist in crafting diet training casts for Albedo where she sought a method to lose weight. The blacksmith also created various other cast designs for commercialization though it was determined that it would not be feasible given that humans would not be able to carry the load comfortably.

The blacksmith was said to have helped Demiurge and Pandora's Actor utilize the research from Sophie Noia of the E-Rantel Magic Research Institute, to create a new equipment using Chaos Stones to allow users to safely operate within a "chaos environment" beyond the Crack on the "other side".

Abilities and Powers
The Chief Blacksmith appears to possess superb skills as a craftsman, as the NPC was able to create a suit of Momon's armor, complete with replicated damage. For example, the scorching and damage on the armor was enough to fool several veteran Magic Casters and blacksmiths when they examined it.

Amanomahitotsu
Chief Blacksmith served as his apprentice.
