The thing that I like about this is that because of the fact that he used a low tier monster, is what made it much easier for him to absorb all of the mana cloud, Lower tier monsters are the only ones with a small enough amount of mana for this to succeed someone who used a high or medium tier monster probably would fail at that step in constructing the gear. And no one else with a low tier monster would bother to learn this technique because if they want to be strong they will get higher tier monsters and if they don't care about being strong they won't spend the effort
