He already had his flames, and his Telekinesis could build the framework of every instrument he desired, what he just needed was a Reagent or an Ability that could mimic something similar, and he could begin attempting forging.
This was something that could assist him now, but was critical to his future, if he planned not to ravage and destroy every world he came across then it was necessary he had this Ability to Forge Alchemical Items on his own.
The uses were endless, but if he needed to seize worlds and fortify them one at a time, he would need defenses, ships, armor for his soldiers, Terraforming Equipments, Buildings, Boats, and so many others.
Before he developed a sizable population that could govern and develop his worlds properly he would need to do that himself. It was a lot of work, and he looked forward to it.
