Belbe - Powerstone strength

She picked up the cast-off Phyrexian discharger. The jewels on the top were dark. Belbe turned the weapon over and discovered the powerstone was gone. Someone-presumably Crovax-had removed it during the melee. An impressive feat, considering he'd never handled such a device before. He'd also removed the powerstone without the special tool, barehanded. An ordinary man would have been struck dead by the potent energy stored in the stone.
