Perfect. Kain backs off just enough to avoid getting struck himself, as the lightning sizzles and crackles through the air... and into the demon. While it's stunned is the best time to act. Kain charges in rapidly, his lance slashing into the monstrous figure. It's... always hard to tell what might be the most vital part of these creatures... so he just aims to cut deeply, taking advantage of its paralysis to severely damage it. When the demon starts moving again it's clearly weakened.
