Hydra Staff

This staff can summon an Ice Hydra to fight for you. The staff can only be found in the ice chests in the Dungeon, using a Frozen Key. The Hydra can independently do damage, and a lot of it too, making it an ideal partner for facing off against Hardmode bosses. Additionally, the Hydra can be summoned inside walls to search for hidden minerals. The frost hydra will not count towards the number of minions that you can summon and you can only have one frost hydra at the time, regardless of items giving a minion bonus such as the pygmy necklace. The frost hydra remains stationary, and will disappear after a certain amount of time.
