Mandra could throw a couple of spells at the Great Ugor at the beginning of the fight. But Jigak was set to attack any enemy of the Great Ugor's. He wasn't in his right mind, but he could tell that between Alzara, who had trouble keeping up with him, and Mandra, who was leisurely enough to attack the Great Ugor as well, Mandra was the bigger threat.
Jigak targeted Mandra like a starved dog.
He shot off the ground with a flap of his wings like a frog and launched himself toward Mandra. He tanked the lightning bolt with his face. He didn't even flinch when it blasted the skin off his face, laying his white skull bare.
But it took his eyes and sight for a moment, so Mandra dodged his charge by simply gliding to the side and letting him zip past her. Jigak could sense that she moved and reached out with a clawed hand to grab or attack her, but his hand just bounced off the translucent armor around her body.
