Strategy[edit]

Recommendation:

  • Weapon: Range weapon
  • Equipment: Reinforced galaxite equipment or higher

Prepare the arena

The boss does not have a large aggro radius. You can try to prepare the arena around it. Fill up holes, not with bridge, but with ground, as the boss can destroy bridges by jumping.

Optional: Add turrets

Turrets can be used to add additional damage if you have excess materials. Circle the arena with turrets.

Immunity to burning

There are 2 sources of burning immunity. The first one is a set effects from molten gear dropped by this boss. The second one is a cooked effects of Verdant Dragonfish or Elder Dragonfish. Found by fishing in lava.

Optional: Immunity to being slowed by slime

Grub Egg Necklace and Larva Ring set effects can provide this benefit if you don't have enough movement speed to avoid its attacks.

Destroy molten projectiles as quickly as you can

It can heal the boss by a big amount.
