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 that flies around the room, shooting lasers that ricochet several times. It shouldn't be too hard to defeat, since X's shots go right through the crystal, and only the smaller robots are dangerous. Spin Wheel is useful against Magna Quartz as it keeps cutting through the crystal for a while, causing continuous damage.
