In the end, Leon found another way to solve that problem for a while. Leon just had to create Soul Eater using Mind Summoning. Considering how useful that sword was, Leon expected that he would have some difficulty creating it. Still, it looked like he would to level up Mind Summoning to the level max before he succeeds because he barely could materialize half of the weapon with his current mana pool.
"Something is off... while that weapon is handy, it is something that appeared in a world in the third stage of assimilation," Leon said. "I didn't feel a high concentration of mana when I had Soul Eater, so it isn't made of mithril. Most likely, it was weapon enchanted by the light or shadow attribute... but that doesn't explain why I would need so much mana to summon a weapon that appeared in the harvesters' world."
