Of course the real even that had happened before the [Thunder Descent] was fully activated both Light and Mystique quickly went into defensive mode.
Light used her body to block the lightning strikes from hitting Mystique.
Mystique on the other hand created another shield even though it isn't as powerful as her [Aqua Shield] it was still considered somewhat durable.
The two of them manage to survive and they look at Sparky who was lying in front of them clearly exhausted with a bit of apprehension.
That ability is just too powerful if it weren't for Light monsters that are of Water and Wind Type would have taken quite a blow with this ability.
Even if it was Mystique's [Aqua Shield] that is both powerful and durable after all it isn't only a Water Type skill but also a mystic skill that reduces elemental damage.
