Magna Quartz

Magna Quartz (マグナクオーツ) is the sub-boss of Crystal Snail's stage in Mega Man X2. It is an eye-like machine encased in crystal accompanied by a small robot thought to be called Savor Moon R that flies around the room, shooting lasers that ricochet several times. Another is sent out by Magna Quartz after enough time passes. Focus on the Magna Quartz itself, as the tiny robots cannot be destroyed. Silk Shot is its primary weakness. Spin Wheel is also useful against Magna Quartz causing continuous damage as it tears through the miniboss. It is also possible to bring the Rabbit Ride Armor to the miniboss room, but it requires carefully destroying only a few of the crystal blocks leading up to the room and some tricky jumping. The Ride Armor's charging attack can destroy the Magna Quartz in seconds.
