P.S. In theory, there's no need to break through the Humans' defense in a battle (Nagas vs. Humans). You need to kill the Light Elementals, which dispel (remove magic effects), or lure the opponent into dispelling and then place these Elementals in a controlling position. And then everything is simple: Restoration on everyone, Stone Skin, back and forth. I'm a tough Naga with a huge reduction in incoming damage, healing every turn; I can't be killed. But that's just a theory, of course.
P.P.S. By the way, has anyone tested Star Light? How is it in general? Can it be more effective than a well-buffed Chain Lightning spell with artifacts?
