Second Piece Asta Boss Weapon Demon Dweller Sword
The latest Second Piece update brings in a powerful boss and one of the most sought-after weapons in the game—the Demon Dweller Sword. If you’re looking to step up your gameplay and unlock the Magic Knight title, this weapon is a must-have. But first, you’ll need to take down the Asta Boss. This guide will walk you through the steps to spawn the boss, defeat it, and get your hands on the Demon Dweller Sword.
Where to Find the Asta Boss

To begin your journey, head over to Frost Island. This is the only place where the Asta Boss can be summoned. However, simply reaching the island isn’t enough—you’ll need a specific item to spawn the boss.
To summon Asta, you must collect 3 Soul Sands. These are not quest items but lootable drops from chests scattered throughout the world. While they can appear randomly, the best farming location is the Niflheim boss battles, where drop rates are higher and more consistent.
- Head to Niflheim and participate in boss fights.
- Open chests after each boss to find Soul Sands.
- Collect 3 Soul Sands.
- Travel to Frost Island.
- Use the Soul Sands to summon the Asta Boss.
How to Defeat Asta
The Asta boss is no pushover. It’s recommended that you’re at a mid-to-high level and preferably bring some teammates along. Keep moving, learn his attack patterns, and use crowd control or ranged abilities when possible to minimize damage taken.
Demon Dweller Sword Overview
After beating Asta, there’s a chance the Demon Dweller Sword will drop. This weapon is Mythic-tier, which means it delivers top-tier damage and also unlocks a special cosmetic and title.
- Grants the Magic Knight title.
- Comes with AA wings on your back when equipped.
- Has 4 powerful skills, including a Z-move with auto-tracking.
- Can be enchanted for even more damage output.
The Z-move especially stands out due to its tracking mechanic that locks onto nearby enemies, making it easier to land hits even during chaotic fights.
The Demon Dweller Sword is one of the strongest weapons in Second Piece right now, and while getting it requires some effort, the payoff is well worth it. Between its high damage output and unique skills, this blade gives players an edge in both PvE and PvP scenarios. Make sure you’re well-prepared, farm enough Soul Sands, and take your shot at defeating Asta.
