Magnet Sphere

Automated electrical discharge and orb flight

The Magnet Sphere drops from post-Plantera Dungeon skeleton variants, including Blue Armored Bones, Hell Armored Bones, and Rusty Armored Bones. Casting the spell expends 14 mana to launch a slow-drifting orb of concentrated electricity. While floating forward, the sphere automatically fires piercing laser beams at any nearby hostiles, dealing 48 base magic damage with 6 knockback until it hits a solid tile or dissipates.

Secondary support utility and spell rotation

Only one sphere can remain active per player at a time, making it an ideal supplementary weapon for mages. Players typically deploy a sphere into an arena before switching to direct-fire spells such as the Spectre Staff or Inferno Fork, allowing the autonomous zaps to provide consistent passive damage. It is especially useful in cramped dungeon chambers where the orb travels slowly down hallways. The Mythical modifier provides the best enhancements to damage, velocity, and mana efficiency.

Trivia

• The orb moves slowly enough to linger inside boss arenas, zapping targets repeatedly over its lifetime.
• Laser zaps from the sphere target the nearest visible enemy automatically without requiring line-of-sight aiming.
