While searching for Illusion Skill to change his Illusion Multiplier, he came across a quite interesting skill.
Skill: Illusion Construct (B)
Effect: The user can change illusions into tools, objects, weapons and other items.
He never thought he would come across a skill like this because this kind of skill was close to that of creation. Since the skills couldn't create living beings along with the fact everything was only an illusion and not a real thing, he understood why the skill was only a B Rank Skill.
Even then, the skill requirement to upgrade was quite cheap compared to the rest and he should have no problem in upgrading this skill to A Rank.
If he combined this skill with his eyes, he would be able to create a realistic illusion or effect. That was why he wanted this skill to replace the Illusion Multiplier.
