Arthur gritted his teeth as he channelled more mana into the circuit, thereby increasing the potency of the spell.
Diana, seeing the scale of the attack, was a little startled at first, but she wasn't a rookie in combat either.
Quickly adapting to the situation, Diana launched several spells to counter the fire released by Arthur while at the same time, her domain worked to suppress the explosion that was trying to destroy it.
If Arthur had initiated a single large spell, then the damage could have been curtailed with relative ease, but with all of his clones isolated all across the domain... Diana had indirectly fuelled Arthur's attack, paving the way for such a level of mass destruction within her domain.
Still, being inside her domain... Diana was the de-facto ruler and the Sovereign of its territory, allowing her to better use the mana at her disposal to reduce the extent of damage Arthur's spell could do to her domain.
