The Endo Hydra Staff is a craftable post-Moon Lord summon weapon that is a direct upgrade to the Staff of the Frost Hydra. When used, it summons a single-headed Endo Hydra at the back of the player, with each resummon consuming one additional minion slot for an extra head. The Endo Hydra itself stays at the back of the player, while the heads fire beams at nearby enemies.

Its best modifier is Ruthless. The Mythical modifier provides the widest array of stat bonuses, but these primarily affect the initial summon rather than the resulting minion. Additionally, minions cannot deal critical hits. The only lasting advantage a Mythical Endo Hydra Staff has over a Ruthless one is knockback.




  • Summoning the Endo Hydra while the player has no free minion slots will cause only the Endo Hydra body to spawn.
  • This weapon can be seen as a counterpart of the Corvid Harbinger Staff, as the two summon weapon's recipes contain post-Plantera items and have similar crafting materials.
