Hydra

The Hydra is a boss monster added by Twilight Forest. The Hydra is a serpent-dragon that spawns with 3 heads. Hydras can be found in a Hydra Lair, which are only found in Twilight Swamps, and Fire Swamps. The main body has health points. Hydras have several attacks:

The Hydra will only take damage from projectiles when the mouth is open and the projectiles are colliding with the mouth area. When a head takes too much damage it will explode and disappear, though it will be quickly replaced by two more heads. When slain it drops a Hydra Trophy, several dozen Hydra Chops, and several vials of Fiery Blood.
