Staff of the Frost Hydra

The Staff of the Frost Hydra (also known as the Hydra Staff) is a magic weapon that has the ability to summon a stationary Frost Hydra for a minute at the cost of 20 mana, which has ranged summon attack with a base damage of 100, acting as a turret. Once cast, the player can switch to another weapon and the Hydra will remain. Unlike true minion summoning weapons the staff only supports one Frost Hydra at any given time, and it does not count towards the minion cap, but trying to summon a second Hydra will cause the first to disappear regardless of other minions. The high damage and tracking nature still makes the staff a valuable extra weapon. Frost Hydra will vanish 60 seconds after casting.

The Hydra Staff is only found in a Frozen Dungeon Chest within the Dungeon, which must be unlocked with its corresponding Dungeon Key.

The best prefix for this weapon is "Mythical".

Trivia

 * The Hydra's attack will not trigger the healing effect of Spectre Armor.
 * The Stationary Nature of the Hydra this staff summons is likely a reference to the Diablo 3 Wizard skill rune effect by the same name, which costs 20 mana and summons stationary Hydra that will attack nearby enemies for cold damage.
