Geniserius wasn't stupid, and he knew the fire giant well enough to guess that he would rather die fighting than be led to a slaughter. He used one of his readied dimension door spell-like abilities to get out of the circle, and reappeared behind the two magic users, and then pointed at the area between the two. They were JUST close enough together that they were in range of his blast spell, and he quickly used it, the massive explosion revealing where he was even as the anti-magic spell went off, covering both the females, and watched the pieces of the two fire giant mages fly in every direction, ignoring the twinge in his gut as the spell tore open a section of scales.
