Nira raised her index finger, "First, should you use a skill and it fails, it should contribute to another skill in any way possible upon its failure in a way that it boosts another skill. You can set this in skills according to your skills' effects and activation."
"And second," Nira raised her second finger before she continued, "You can execute a skill and then execute another skill that can combine with it such that their combined effect should be greater than the sum effect of those two skills individually. All of your skills should be able to do this."
"Synergizing skill is a basic thing. In Mind Zone where you instantly create skills with Soul Vices included to counter your opponent who is also doing the same, your skills should also be able to synergize there."
