Urza - Regenerative weakness

She cast a quick series of spells, prepared and laid aside for this very moment. All defenses were stripped from Urza’s head. Her fingers grew as long and sharp and curved as daggers. She drove them into his skull. They punched through bone and into his frontal lobe.

Urza roared, reconstituting shattered bone and ruptured brain.

She was not done, though. Her fingers curled into claws. She raked through gray matter and shattered sinuses and optic cavities. She scooped up the gemstones that were his eyes. With a brutal yank, she hauled them forth.

Blind and gaping, his head staved, Urza struggled against tumbling walls of pain.

He clutched to her. She was all that kept him aloft.

He had to heal.

He had to rebuild his being.

He could not. Part of that being—the only part that was not a mere projection of his mind—had been ripped away. Those gems defined him.

Even in his dying agony—for, yes, he was dying: his power was also his weakness—Urza realized how like Karn he was. They were both defined by stones set in their heads. Both lived with them and died without them. Mightstone and Weakstone—they were Urza’s affective and cognitive cortex. Without them, he was destroyed.
