Staff of the Frost Hydra



The Staff of the Frost Hydra is a Hardmode post-Plantera sentry summon weapon. It summons a stationary Frost Hydra for two minutes at the cost of 20 mana. Once summoned, the Frost Hydra acts as a stationary turret, which fires magic ice pellets whenever enemies are within its roughly 60-tile range. It will automatically angle its head up and down, and turn left and right, to target enemies in any direction. The Staff of the Frost Hydra is always found in the Ice Chest within the Dungeon, which must be unlocked with its corresponding Frozen Key.

The Frost Hydra can be summoned anywhere on the visible screen, even if blocks completely separate the player from the point clicked. It cannot, however, be summoned in the air, and will instead appear on the closest block or platform below the summoning point. The Hydra inflicts Summon damage, but as a sentry, it is stationary and temporary. It does not count toward the caster's minion limit, and any previous sentry will vanish when a new one is summoned.

Tips

 * The high damage, versatile remote placement capability and lighting effect makes this Staff a valuable auxiliary weapon.
 * The remote capabilities of the Frost Hydra make it useful for battles and invasions, since it can be placed and left alone to slay enemies while the player does other things, such as making purchases, hiding, or fighting enemies in a different location.
 * The Frost Hydra will fall when blocks below it are removed, making it useful for guarding the player while digging vertical tunnels.
 * The Frost Hydra can be extremely strong in PvP because it is possible to summon on a player over a wall to kill them easily.
 * The Frost Hydra can also be useful in exploring caves as it can be summoned inside blocks and emits light.
 * The Frost Hydra can attack enemies even after the player has died.

Trivia

 * In Diablo 3 there is a rune called Frost Hydra which is very popular in Wizard builds because of its increased damage and limited AOE potential.
 * Unlike the in Greek mythology, the Frost Hydra sentry only has one head.
