Hydra
Hydra is an open-world wilderness boss with 25,000 Hull and a 20-minute respawn after defeat.
Finding the boss
The Hydra inhabits the central wilderness.
These are shared world encounters. Sail to the boss; the old scheduled instance portal is not the entry route.
Warnings and attacks
Each marked attack block covers 3 × 3 normal movement tiles. Patterns cover a 39 × 39-tile field around the boss, omitting complete blocks that touch land.
Hydra cycles through 5 patterns. The warning lasts 1.5 seconds, followed by impact and 1.2 seconds of recovery. Pattern hits deal 100 damage before the normal damage/death handling.
Separate targeted volleys select up to 5 eligible sailors on a rotating basis and mark their positions. Move out of the marked block before impact to avoid the hit. These volleys roll from zero to 100 damage. Pattern and volley warnings share one timeline.
Combat and loss rules
Wilderness level 5 and above is multi-combat. In single combat, party members can share an NPC encounter, but party membership never permits multiple players to pile onto one player.
Dying to the boss follows normal PvE loss rules; a player kill follows normal wilderness PvP loss rules. There is no special instance protection for carried items.
After the encounter
After defeat this boss respawns in 20 minutes. The old daily, weekly and monthly opening schedules do not gate these wilderness spawns.
