Hydra is a Second Sea encounter with three stages and a chest reward. Its spawn progression is linked to Sea Kings: the community wiki and an independent player discussion both describe three Sea King defeats before Hydra. The wiki infobox summarizes the cycle as four hours, while the older wiki describes another hour after the third Sea King. These descriptions should not be turned into a promise that joining a server starts a personal four-hour countdown.
The first stage can move and dive, with projectiles and a broad roar. Stage two remains in the arena and attacks nearby players. The last stage centers on Hydra Body while summoned minions threaten the surrounding area. The practical editorial priority is to identify the stage and attack source before choosing where to stand: surviving a mobile first phase does not make the stationary body phase harmless.
The current community wiki lists one million HP for Hydra I, 1.1 million for Hydra II and one million for Hydra Body. The older wiki lists 1.1 million, 2.2 million and two million respectively. The newer article also contradicts itself on minion health, giving one billion in its overview and ten billion in its detailed notes. The comparison table preserves those figures by source instead of selecting one apparent maximum as confirmed.
After the final stage, rewards come from a chest among four tiers. The wiki and a separate player discussion both distinguish Hydra's four chest tiers from Sea King's three. Chest tier and individual item chance are different questions; an unknown chest probability is left blank rather than inferred from an old patch. Use the boss-drop catalog for named rewards and keep the source date beside any historical percentage.
