Magnet Sphere

The Magnet Sphere is a Hardmode magic weapon which casts a glowing sphere where the player aims.

It travels in a straight line for 7 seconds, rapidly dealing damage to the closest enemy to the orb. It will disappear if the central orb hits a solid object or has gone 52 blocks. Only one sphere can be present on screen, if the player casts another, the previous one will fade away.

You can obtain it as a rare drop from the Blue Armored Bones, Rusty Armored Bones, Hell Armored Bones or Bone Lee in the Dungeon.

The Magnet Sphere attack looks like this

Tips

 * This weapon is best used in conjunction with the Spectre Armor, since it does a great amount of damage very fast, meaning an important healing capability.
 * It is not advised to use the Magnet Sphere in an enclosed space as the sphere will not stay onscreen long enough to deal a great amount of damage.
 * This spell can be used to combo well with Crystal Storm and Golden Shower Recommended method is to cast Magnet Sphere, hose the enemies down with Ichor, then start spraying crystals into the crowd.
 * The Magnet Sphere does not appear to have the "auto-targetting" laser effect in PvP. If the sphere contacts another player it will still damage them however

Trivia

 * The sphere acts similar to iD Software's BFG 10K from the game Quake II, emitting lasers at enemies nearby. The Magnet Sphere doesn't explode, but instead fades away and doesn't cause any splash effects.
