Lava Stone Guardian is particularly vulnerable to Wind and Dark attributes, making these elements crucial in your strategy. One of the boss's key mechanics is the reduction of incoming damage when its Break gauge is active, combined with a special pattern that summons a volcano onto the battlefield. Given Lava Stone Guardian’s formidable durability, defeating this boss within the time limit requires a powerful burst DPS capable of delivering significant burst damage.

Main Damage Dealer (Top Priority) – Amamiya Mirei

Amamiya Mirei is currently the only character capable of delivering both burst and sustained damage with Wind and Dark attributes, making her essential for taking down Lava Stone Guardian.

Break Hunter (Second Priority) – Woo Jinchul or Lim Tae-Gyu

When selecting a Break Hunter, you only need to include one of them in your lineup. Woo Jinchul is often preferred due to his easier acquisition and user-friendly control.

Additional Hunter (Third Priority) – Min Byung-gu, Han Semi (Upcoming)

For the final slot, consider placing Min Byung-gu or the upcoming Han Semi to support the burst DPS, Amamiya Mirei. Although Han Semi has not yet been released, developer livestreams have revealed that she will possess abilities like mana recovery and shield generation, making her a valuable asset in aiding Mirei during battle.
