Miguel stared at the Red Sparrow that had began to condensed the [Fireball] skill.
He recalled that this was the first attack that they launched towards his Volcanic Tortoise back then.
However, unlike back then, the Red Sparrow did not launch the [Fireball] immediately.
The Red Sparrow had it's beak pointing in mid-air. The [Fireball] stayed above its beak. Its size grew larger and denser the longer it stayed on it's beak.
Seeing the scene that resembled Aaliyah's perfect control of her fires, Miguel thought that this should be Erika's Innate Skill, [Accumulate].
According to what he knew, her Innate Skill, [Accumulate], allowed her to compress and strengthen her atack to another level.
For example, her normal Level 1 [Fireball] could be strengthened to Level 2.
She could do this infinitely as long as her energy supports it.
