Rank 3 Celestial Prime
Draco directly took out a lump of Common Iron and refined it into a clone of Excalibur, his very first Rare sword he had received when opening the Rare weapons chest (Sword) that was part of the Master Package. The energy drain from this was extremely intense, leading to an entire area around Draco being completely drained of both Worldly and Aetheric Energy for more than 5 minutes.
His lips twitched. Well, now he understood one of the reasons why Norma had left the Divine World to live in her own small world, as the energy there was far more potent and less distributed.
He wondered how she had managed when she was at the mortal stage and hadn't yet mastered the energy consumption control when refining.
Draco tossed the sword into the Guild Shop. Some serf player out there would probably buy it since they had access to the Guild Shop too and actual members of Umbra were above using mere Rare weapons at this point.
