All Sea Events and How to Start Them in Haze Seas Roblox

Sea Events are where a lot of the best late-game farming in Haze Seas happens, but most of them are not events you can casually trigger whenever you want. Some run on server timers, some require a Storm, and others need a specific summon item or sacrifice before the boss appears.

Use the table first to know where to wait, then use the event sections below for the exact start condition and the prep that matters before the timer hits.

Haze Seas Sea Events table

The main split is simple: Sea 2 is where you should watch for Shrine and Storm activity, while Sea 3 adds several of the strongest event chains, including Ghost Ship, Wandering Merchant, and more end-game material farming.

Preparation before farming Sea Events

Before you start camping Sea Events, keep the server chat visible. The strongest events often give a warning or announcement, and arriving late can mean missing the damage window, altar summon, merchant stock, or boss attempt entirely.

You should also be in the correct sea before the timer is close. Bring enough damage for raid objects, enough Devil Fruits or crafted materials for summon events, and a build that can survive end-game bosses rather than only tagging them once.

Treasure Shrine Raid in Sea 2

Treasure Shrine Raid is a Sea 2 raid that appears in one of three possible locations. The server announces that the Treasure Shrine has been spotted shortly before it starts, so the real race is getting to the shrine quickly and dealing enough damage before the vault window closes.

Once the raid begins, players get 5 minutes to destroy the main vault or chest inside the shrine. Its health sits around 2-3 million HP, so this is not a casual low-damage event; you want strong fruit, weapon, and fighting-style damage ready before the announcement appears.

The number that matters most is the 10% damage threshold. If your build cannot reach it inside the short raid window, you may be present for the event but still miss the rewards that make Shrine farming worth your time.

Storm Event in Sea 2 and Sea 3

Storm is the hub event for a large part of Haze Seas end-game progression. It can happen in Sea 2 and Sea 3, lasts about 10 minutes, and currently runs on a timer of around 2 hours 30-35 minutes.

Zenith Boss at Shadow Island

Zenith Boss is a Storm-linked boss that appears underground at Shadow Island. If a Storm starts and Zenith is your target, go there immediately instead of chasing open-sea activities.

Zenith matters because it is tied to major progression, including Race V2 and the Zenith Sword / 3SS route. That makes Storm timing important even if you are not farming Ghost Ship or Cthulhu yet.

Ghost Ship altar and fruit points

Ghost Ship is a Storm-gated event. During a Storm, look for the green Ghost Altar near Starter Island or the Sea 3 altar area, then sacrifice Devil Fruits worth a total of 20 points.

The summon is based on fruit rarity, not the raw number of fruits. A single Mythic fruit reaches the full cost by itself, while lower rarities need to be combined carefully.

Do the math before you reach the altar. For example, Legendary + Rare is enough, but a stack of Commons takes much longer to feed into the event and can waste Storm time.

Cthulhu summon requirements

Craft the Prismatic Shard

Combine Phantom Lantern, Dragon Heart, Sea Beast Heart, Ryujin Core, and Saturn’s Ring.

Wait for a Storm

Cthulhu is tied to the Storm window, so keep the shard ready before the weather starts.

Find the whirlpool

Move to the whirlpool once the Storm is active.

Use the Prismatic Shard

Activate the shard at the whirlpool to summon Cthulhu.

Prepare for the boss fight

Cthulhu is level 10,000 and has two separate health bars.

Red Emperor throne room event

Red Emperor appears inside the throne room on a 4-hour timer. This is a timed boss event, so you are waiting for the spawn rather than crafting a summon item.

You can speed up the timer by defeating super bosses. Each super boss kill cuts 10 minutes from the wait, up to a maximum reduction of 2 hours.

Because Red Emperor sits on a long cycle, it is better to fold it into a broader farming route instead of standing still for the full timer. Chain super bosses when your server is active, then rotate back to the throne room when the reduced window is close.

Ryujin Boss on Rainbow Sky Island

Go to Rainbow Sky Island

Start the event route at Rainbow Sky Island.

Defeat 500 enemies

Kill 500 enemies on the island to meet the summon requirement.

Fight Ryujin

Once the requirement is complete, Ryujin appears.

Keep the Ryujin Core

Save Ryujin Core if you are working toward the Cthulhu Prismatic Shard craft.

Saturn Boss at Egghead Island

Saturn Boss is tied to the pirate attack event at Egghead Island. The attack cycle happens every 1 hour 15 minutes, making Saturn one of the easier boss timers to work into a repeated farming route.

Defeating Saturn gives valuable rewards and progression materials. If you are preparing for Cthulhu, keep Saturn’s Ring in mind because it is one of the materials used to craft the Prismatic Shard.

Dragon Hybrid trumpet summon

Search random chests

The special trumpet can appear in random chests around every 2 hours.

Farm Sea 3 NPCs if needed

Sea 3 NPCs have a very small chance to drop the trumpet.

Use the trumpet

Activate the trumpet to summon Dragon Hybrid.

Separate it from the release event

The Dragon Hybrid release event window is separate from the recurring trumpet summon.

Wandering Merchant in Sea 3

Wandering Merchant is a Sea 3 event with a spawn window of about 1 hour 30 minutes to 2 hours 30 minutes. When the merchant appears, chat announces it, and the NPC can spawn at one of four Sea 3 locations.

The important part is speed. Wandering Merchant despawns after 7 minutes, and the event can end immediately if another player buys an item first.

If you are merchant hunting, stay in Sea 3, keep enough currency ready, and move as soon as the chat message appears. Treat the announcement like a race, not a reminder.

Sea Beasts and recurring sea farming

Sea Beasts are recurring sea encounters used for farming Gems, Bounty, Sea Beast Cores, and Sea Beast Hammers. Rocky Pillars and similar sea hotspots are the main places to include them in your route.

For smoother farming, aim for at least level 700+, use a sturdy ship with around 2500 HP or more, and bring mobility-friendly fruits such as Ice or Light. Older exact Sea Beast stat tables can shift after major updates, so use readiness checks over fixed damage math.

Farming order and mistakes to avoid

If you are not fully end-game yet, start with repeatable farming that builds your materials and currency before committing to the hardest Storm bosses. Sea Beasts and Shrine attempts help you build resources, while Storm windows should be saved for clear goals like Zenith progression, Ghost Ship summons, or Cthulhu attempts.

Once you reach Sea 3, add Wandering Merchant checks between timed bosses. The best route is not just killing whatever appears first; it is being in the right sea with the right materials before the event timer opens.
