Opal smashed her broadsword against the floor, tip first. A dome of fire covered her from all directions, destroying not only Merry's offense but also Nyssa's sneak attack as birds made of frost dove from the sky.
The fire of the dome did not simply extinguish. Despite weakening, it was sucked back into her sword, and the redhead sent a fiery slash fire at Nyssa who was already retreating. Nyssa seemed to know a lot about her sister's tactics, meaning she had watched her fight before.
Merry, her selfish personality reflected in her battle strategy, chose to use that attack to find an opening in Opal's defenses and let Nyssa block the heavy strike on her own.
A slight grimace made it through the usually impassive and frost expression, but the white-haired fairy drew a circle in the air, and five plates of ice appeared in the air. A bead of sweat formed on her forehead despite the irregular chilly temperature around her.
