All Sea Events in Haze Seas Guide (Treasure Shrine, Storm, Ghost Ship, Cthulhu & More)!

Exploring the ocean is one of the biggest parts of Haze Seas. Besides leveling up, collecting Devil Fruits, and farming bosses, you’ll also spend a lot of time participating in Sea Events. These events reward players with Gems, levels, rare crafting materials, titles, and even powerful fruits that are needed for late-game progression.

Some Sea Events happen automatically on a timer, while others require players to complete special objectives before a boss appears. If you’re aiming for Race V2, Race V3, weapon upgrades, or endgame crafting, learning every Sea Event is extremely important. Here’s a complete guide covering every Sea Event currently available and those planned for future updates.

1. Treasure Shrine Raid

The Treasure Shrine Raid is one of the most rewarding events in Sea 2. The shrine appears once every 1 hour and 45 minutes after the previous raid ends. It can spawn at one of three different locations in Sea 2, so players should pay attention to server announcements before searching.

Server Messages

Before the event starts, you’ll receive:

• “The treasure shrine has been spotted in the sea…”

Thirty seconds later, the raid officially begins.

• “WARNING: The shrine has surfaced. You have 5 minutes to destroy the central vault!”

If players fail:

• “WARNING: The vault was not destroyed in time and the shrine is now sinking.”

If players succeed:

• “Success. The vault has been destroyed in time!”

How to Complete the Treasure Shrine

Inside the shrine is a massive treasure chest with around 2 to 3 million HP. Players have only five minutes to destroy it. If the timer expires:

• The vault doors close.
• Water fills the room.
• Every player inside instantly dies.

Because of this, bringing multiple players greatly increases your chances of clearing the event.

Treasure Shrine Rewards

Players dealing at least 10% of the total damage receive:

• 30,000–80,000 Money
• 1 Level
• 25 Gems
• 100% Shrine Relic (Legendary Material)

The player who deals the highest damage also receives:

• One random Rare or higher Devil Fruit

The fruit uses odds similar to the Robux Fruit Spin.

Treasure Shrine Titles

Available titles include:

• The MVP — Deal the most damage and receive the fruit reward
• Shrine Plunderer — Clear 1 Shrine Raid
• Shrine Conqueror — Clear 20 Shrine Raids
• Relic Raider — Clear 100 Shrine Raids
• Drowned — Die after the shrine floods

2. Storm Event

Storms are another important world event. They occur every 2 hours and 35 minutes in both Sea 2 and Sea 3 and remain active for 10 minutes. Several exclusive bosses and activities are only available while the storm is active. During storms you can access:

• Zenith Boss
• Ghost Ship
• Cthulhu Boss
• Various endgame quests

Always pay attention whenever a storm begins.

Zenith Boss

During the Storm Event, the Zenith Boss appears underground on Shadow Island. This boss is required for:

• Zenith Sword
• Three Sword Style progression
• Race V2 Quest

If you’re working toward late-game weapons, you’ll eventually need to defeat Zenith several times.

3. Ghost Ship Event

The Ghost Ship is an unreleased Sea 3 event tied to the Storm system. During every storm, a Green Ghost Altar appears near the starter area. Players must sacrifice fruits worth 20 points to summon the ship. Fruit values include:

• Common = 1 Point
• Uncommon = 3 Points

6. Wandering Merchant

The Wandering Merchant is another planned Sea 3 event. He appears every 1 hour 30 minutes to 2 hours 30 minutes in a random location. The merchant sells:

Each item may only be purchased once.

If every item is bought, the merchant immediately disappears.

Sea Events are some of the most rewarding activities in Haze Seas, especially once you reach Sea 2 and Sea 3. Treasure Shrine Raids provide reliable Gems and Shrine Relics, Storm Events unlock exclusive bosses, while Sea 3 bosses drop materials needed for some of the strongest weapons, Race upgrades, and awakenings in the game. If you want to progress efficiently, it’s worth learning each event timer and joining whenever one appears, since many endgame items can only be obtained through these limited-time encounters.
