If Plasma Bullet was much smaller but consumed one-third of the mana Magma Spear consumed, then the potential of the skill was there. However, since that was the case, Leon couldn't afford to learn other forms of attacks by combining elements. To maximize the potential of that skill, Leon had to learn different spells that consumed less mana and level up them to obtain status points, and he felt quite satisfied after doing that for a month.
