Tempest Staff

The Tempest Staff is a Hardmode summon weapon. It spawns a small tornado (or "Sharknado") that follows the player for an unlimited amount of time, and attacks enemies automatically by firing shark-shaped projectiles which splatter against enemies and blocks. Its attack is akin to a miniature version of Duke Fishron's tornado/shark attack. The Tempest Staff has a 20% chance of being dropped by Duke Fishron.

The Tempest Staff's tornado moves to intercept enemies at significant range, and can pass through blocks. The tornado itself also damages enemies on contact.

Tips

 * Even though the sharks deal a lot of damage, they are not very accurate due to slightly arcing mid-flight. They sometimes fail at hitting quick enemies. Despite this flaw, the Sharknado itself is non-solid (can pass through all blocks) and attack enemies outside of the player's sight.
 * As the tornado itself deals damage to critters, take care when using the staff while catching them.
 * They are somewhat useless in small areas because they hover over the player's head. Consider using the Optic Staff because the eyes will hover and hit solid blocks.

Trivia

 * This weapon is a reference to the 2013 movie "Sharknado", which features a tornado filled with sharks.
 * Even when PvP is turned on, like all other summons, Sharknadoes will not attack players.
 * Summoned Sharknadoes will turn translucent when passing through blocks, similarly to what Duke Fishron and Pigrons do.
 * The Tempest Staff has the highest base damage of all minion-summoning staves, with the exception of the sentry Staff of the Frost Hydra.
 * The Tempest Staff displays an odd tooltip on the : 1 minute duration. This is a bug, and the Sharknadoes will follow the player indefinitely.
 * It is the only weapon dropped by Duke Fishron that doesn’t have its color scheme.
