Sailor Piece Dio (The World) Melee and Boss Guide
He’s got the whoooole world in his hands.

The long-awaited Dio Spec, also known as The World, is now available in Sailor Piece, but there are a fair few requirements to meet when obtaining it. Firstly, you need to unlock the Sea 2 map in Sailor Piece.
Sailor Piece Dio
Dio has finally arrived in Sailor Piece, but he’s locked behind Sea 2. Not all players have access to the new map, though, as they don’t meet the specified requirements. This means The World Spec is only available for those who are able to travel to the Sea 2 islands.
How to Unlock Dio (The World)
Before you worry about the required items, you need to visit Bizarre Island at Sea 2 to find The World Trainer NPC.
- 6x World Cores
- 2.99% chance to drop from The World (Boss)
- 2x Vampire Omens
- 1.25% chance to drop from The World (Boss)
- 20x Power Fragments
- 39.92% chance to drop from The World (Boss)
- 12x Time Remnants
- 13.72% chance to drop from The World (Boss)
- 80x Dominion Brands
- Chance to drop from Strong Bandit NPCs
- Primordial (Bloodline)
- Reroll your Bloodline with Bloodline Stones, dropped from Sea 2 NPCs and Sea Beasts
- DMG +27%, Maximum HP +40%, +1 Drops +15%, Luck Multiplier +15%, DMG Reduction +5%, and Melee DMG Multiplier +10%
- Time Tyrant (Title)
- 0.60% to 1.2% chance to drop from The World (Boss)
- Increases your DMG by 92.5%
The World Boss
From the list above, you can see that the vast majority of required items when unlocking Dio’s Spec require you to defeat the boss known as The World. This boss does not spawn naturally and instead must be summoned with the use of Dominion Shards.
The amount of Dominion Shards required changes depending on the difficulty of the boss fight:
- Normal Difficulty
- Requires 1x Dominion Shard
- Medium Difficulty
- Requires 2x Dominion Shards
- Hard Difficulty
- Requires 3x Dominion Shards
- Extreme Difficulty
- Requires 4x Dominion Shards
How to Get Dominion Shards
Dominion Shards, like the Dominion Brands, are a potential drop when defeating Strong Bandits.
Obtaining the F Ability For Dio (The World)
To get the F ability for the Dio Spec, you first need to speak with The World Trainer NPC on Sea 2’s Bizarre Island. The requirements he asks for are:
- Defeat the Cosmic Being (Boss) 10 times whilst having the Dio Spec equipped
- Defeat The World (Boss) on Hard or Extreme Difficulty a total of 20 times
- Defeat Sea Beasts (Sea Serpent or Kraken) 10 times whilst having the Dio Spec equipped
- Timestop NPCs 250 times by using Dio’s V ability
As well as the new move, your DMG increases by a further 30%.
Frequently Asked Questions
What Are The Best Specs in Sailor Piece?
I’ve got a Sailor Piece Melee Tier List, which ranks all Specs from best to worst. If you notice any Specs are missing, it may be because I’m still taking my time to test them out. If you’re curious about whether or not the Dio spec is worth getting, the tier list may come in handy.
How Do I Unlock Sea 2?
Sea 2 requires a minimum player level of 12,500, an Ascension Level of 5, and the completion of the Sea Traveler’s quests. The first quest entails finding 2 Ancient Fragments, and the second involves collecting 7 Map Pieces.
