Haze Seas: How to Get Black Leg V2 in Roblox

Black Leg V2 is the upgraded form of the kick-based Black Leg fighting style in Haze Seas. It hits harder than the base version and comes with an updated skill set, but unlocking it is a late-game task that requires reaching the Third Sea, grinding mastery, and farming a boss event for a specific drop.

Quick answer: Buy Black Leg V1 for 50,000 Beli, reach Mastery 300 with it, then bring 2 Phantom Lanterns and 5,000,000 Beli to the Sage of Combat on the Sea 3 Starter Island to unlock Black Leg V2.

Black Leg V2 requirements in Haze Seas

Everything needed to complete the upgrade is listed below. You cannot skip the V1 step, since V2 is an evolution of the style you already own.

Requirement	Detail
Own Black Leg V1	Bought for 50,000 Beli at Sea Restaurant in Sea 1
Mastery	300 on Black Leg V1
Sea access	Third Sea (Sea 3) unlocked
Materials	2× Phantom Lantern
Currency	5,000,000 Beli
Upgrade NPC	Sage of Combat, Sea 3 Starter Island

Buy Black Leg V1 and reach Mastery 300

Sail to Sea Restaurant Island in Sea 1 and speak to the Black Leg Trainer NPC. Pay 50,000 Beli to learn the base style, which is the cheapest fighting style in the game.

Equip Black Leg and grind its Mastery to level 300. Mastery builds up as you land hits and defeat enemies with the style, so use it as your active fighting style while clearing mobs.

Unlock the Third Sea by completing its unlock quest, then travel to the Sea 3 Starter Island. This is where the upgrade NPC lives, so you need Sea 3 access before the V2 path opens.

Farm Phantom Lanterns from the Ghost Ship

Phantom Lanterns are the hardest part of the upgrade. They have a 100% drop rate from the Ghost Ship, a boss event that only spawns in the Third Sea. You need two, so you will run the event at least twice.

Travel to the Land of Gods in Sea 3 and go to the left side of the island to find the green Ghost Altar. The altar only appears during a Storm, which occurs roughly every 2 hours and 35 minutes, so wait for one to begin before attempting the event.

Offer Devil Fruits at the altar to build up 20 points. Fruit rarity sets how much each offering is worth, so a single Mythic fruit reaches the threshold instantly, while lower-tier fruits stack toward it.

Fruit rarity	Points
Common	1
Uncommon	3
Rare	5
Legendary	15
Mythic	20

Once you hit 20 points, the Ghost Ship spawns and you will see the message “A phantom ship rises from the abyss…” Defeat the ship to claim a guaranteed Phantom Lantern, then repeat the event to collect the second one.

Beating the ship also rolls a few extra rewards on top of the guaranteed lantern.

Reward	Drop chance
Phantom Lantern	100%
Ghost Chest	Guaranteed
Blade Fragment	10%

Unlock Black Leg V2 at the Sage of Combat

Return to the Sea 3 Starter Island with Mastery 300, both Phantom Lanterns, and 5,000,000 Beli in your inventory.

Speak to the Sage of Combat NPC and confirm the upgrade. Handing over the two lanterns and paying the 5,000,000 Beli fee learns Black Leg V2.

When it works, your Black Leg style switches to its V2 kit and you earn the “Leg of Fury” title. If the Sage will not complete the exchange, the usual causes are Mastery below 300, fewer than two Phantom Lanterns, or not having the full 5,000,000 Beli on hand.
