Deadly Sphere Staff

The Deadly Sphere Staff is a Hardmode, post-Plantera minion-summoning weapon that summons a Deadly Sphere character to fight on the player's behalf. The Deadly Sphere flies continuously and charges at enemies to inflict damage. It cannot attack through blocks. The Deadly Sphere has several visual forms, which it periodically transforms between after it attacks 3 times, though this has no functional effect. The Deadly Sphere Staff is dropped by Deadly Spheres during a Solar Eclipse.

As with most summoning weapons, the Deadly Sphere Staff's best modifier is Ruthless, which gives the highest boost in damage. Its funniest modifier is Deadly.

Trivia
