Staff of the Frost Hydra

The Staff of the Frost Hydra is an item introduced in patch 1.2. It has the ability to summon a Frost Hydra which does between 100-135 ranged magic damage. It has no initial summon damage and cannot move, acting as a turret. The staff only supports one Frost Hydra at any given time, so trying to summon a second Hydra will cause the first to disappear. The Frost Hydra is useful for protecting against blood moon mobs and for dishing out extra damage to more difficult bosses. The Staff of the Frost Hydra is only found in a Frozen Dungeon Chest within the Dungeon, which must be unlocked with its corresponding Dungeon Key.
